A US trademark docket hangs on a date the Office assigns and nobody can move: the registration date. Taiwan trademark docketing hangs on a date you partly control. Article 33 of the Trademark Act runs the ten-year term from publication of registration, and publication happens only once the registration fee is paid under Article 32 — so the applicant’s payment timing propagates into every renewal the mark will ever have. Taiwan is also outside the Madrid System entirely, which means no central renewal reaches it. Here are the eight dates, with the Article behind each.
Why Taiwan Trademark Docketing Starts With a Date You Control

Nearly every country guide to Taiwanese marks opens with the same four facts: ten-year term, six-month renewal window, six-month grace period, three-month opposition. Those facts are right. They are also not where Taiwanese portfolios are lost.
The structural oddity of Taiwan is this. In most registration systems the date your renewal chain hangs from is handed to you by the office — the registration certificate issues, and every downstream deadline follows from it. In Taiwan the anchor date is set by publication of registration, and publication only happens once you have paid the registration fee.
Read Articles 32 and 33 of the Trademark Act together and the consequence is unavoidable: the date from which the ten years run is downstream of a payment the applicant controls the timing of. Pay promptly and the anchor falls where you expect. Pay in the second month, or pay late under the Article 32(3) relief, and the anchor moves with you.
That is a docketing problem rather than a legal one, and it is exactly the kind of problem a US-built system handles badly, because US maintenance arithmetic is anchored to a registration date the office assigns and the owner cannot shift.
This guide sets out the eight dates a Taiwanese record needs, each tied to the Article that creates it, each with its anchor stated explicitly, and each marked curable or not curable. Where a Taiwanese clock differs from the US clock a docket is usually built around, the comparison is drawn out rather than left implied.
The Term Under Article 33: Ten Years From Publication of Registration

Taiwanese marks are administered by the Intellectual Property Office (TIPO) under the Ministry of Economic Affairs. Article 33 of the Trademark Act sets the term:
“The proprietor of a registered trademark shall have the exclusive right of the trademark for a period of ten years from the date of publication for registration. The period of the trademark right may be renewed, and the duration of each renewal period shall be ten years.”
The operative phrase is the date of publication for registration. Not the filing date. Not the date of the approval decision. Not the date printed on the certificate when it eventually arrives in the post.
This matters because several widely-read guides to Taiwan — including guides whose substance is otherwise sound — compress Article 33 to “ten years from the date of registration.” In ordinary Taiwanese practice that shorthand lands in the right place, because registration and its publication are near-simultaneous once the fee clears. The shorthand breaks precisely when the fee is paid late, which is the scenario a docket exists to survive.
So Taiwan trademark docketing needs the publication date stored as a first-class field, populated from the Trademark Gazette entry rather than derived from any other date on the record. Deriving it is what produces a ten-year chain that is quietly wrong by weeks or months.
Contrast the anchor families you may already hold. Taiwan runs from publication of registration; the EUTM and Türkiye run from the filing date; the United States runs from the registration date. Our EU trademark docketing deadlines breakdown covers the filing-date family. Mixing the three in one database column is the root cause of most cross-border expiry errors.
Article 32: The Two-Month Fee Clock That Sets the Whole Renewal Chain

When a Taiwanese application is approved, TIPO issues an approval decision. Article 32 then conditions registration on payment:
“A trademark that has been accepted for registration shall be published for registration and a trademark certificate shall be issued, provided that the registration fee has been paid by the applicant within two months from the day following the date of the service of the disposition.”
Three details in that sentence each deserve a field on the record.
The trigger is service, not receipt by you. The two months run from the day following service of the disposition. For a foreign holder that means service on the Taiwanese agent. The day the instructing firm read the report has no standing. A docket that stores “date reported to us” is systematically late by whatever the reporting lag happened to be that week.
The period is counted from the day following. Taiwanese periods are routinely expressed this way, and the Enforcement Rules repeat the formula for priority. One day of drift is immaterial on a ten-year renewal and material on a two-month fee clock.
Publication follows payment. Because Article 33 runs the term from publication, the date on which the fee is paid propagates forward into every renewal for the life of the mark. This is the single most consequential sentence in Taiwan trademark docketing and no guide on the first page of Google for Taiwanese deadlines currently draws the link.
The Article 32(3) Cure, and the Third-Party Carve-Out That Can Remove It
A missed registration fee is not automatically fatal. Article 32(3) supplies a relief route: where an applicant has unintentionally failed to pay within the prescribed period, the applicant may pay double the fee within six months from the day following the date on which that period expired, and TIPO will publish the registration.
That reads like the renewal grace period, and docketing systems tend to model it the same way — a soft landing with a surcharge. It is not the same thing, because the Article carries a proviso: the relief shall not apply if an application for trademark registration filed, or rights of a trademark obtained, by a third party during that period would be affected.
The practical reading is uncomfortable but clear. Between the expiry of your two months and the day you pay double, the register is open. If a third party files or acquires rights in that window and your late payment would prejudice them, the cure is unavailable — and the application is gone.
So the two-month fee deadline should be docketed as effectively uncurable, with the six-month double-fee route recorded as a contingency whose availability depends on third-party conduct you cannot observe or control. Flagging it green in a dashboard because “there is a six-month grace period” mis-states the risk to whoever reads that dashboard.
This is a genuine structural difference from the renewal grace period in Article 34, which carries no equivalent third-party proviso. Two six-month double-fee windows in the same statute, one reliable and one conditional, is the sort of distinction that survives only if someone wrote it into the docketing rules.
Article 34 Renewal: Six Months Before, Six Months After, and No Extension
Article 34 sets the renewal mechanics:
“A request for renewal of the trademark right shall be made, and the renewal fee paid, within six months before the expiry of the period of the trademark right; failing this, the request may be made and the fee paid in double within such further period of six months from the day following the date of expiry of the period of the trademark right.”
Two windows, then. A six-month pre-expiry window at the standard fee, and a six-month post-expiry window at double the fee. Renewal is available for all or some of the designated goods or services, so a partial renewal is a deliberate option rather than an error to be corrected.
Taiwan requires no declaration or evidence of use to renew. There is no Taiwanese analogue to the US Section 8 declaration, and no analogue to the Philippine or Mexican mid-term use filings. A renewal is a request and a fee. That makes the Taiwanese renewal cheap to execute and easy to forget, because nothing in the workflow forces a use review.
Now the detail that almost never appears in a country summary. Article 8 of the Enforcement Rules of the Trademark Act grants a general power to extend statutory periods on request — and carves out Article 34 by name. The period “during which an action should be done pursuant to the Act or these Rules other than Article 34” may be extended on a reasoned request filed before the original period expires.
In other words, the renewal window is the one Taiwanese period TIPO will not extend on request. Most other clocks in Taiwanese trademark practice are, in principle, extendable. Renewal is not. A docket that treats all Taiwanese deadlines as uniformly extendable has the risk profile exactly inverted.
Our international trademark renewal docketing guide covers how to hold renewal calendars that disagree with each other across a portfolio without normalising them into a single wrong rule.
No Madrid Route: Taiwan Trademark Docketing Without a Central Renewal
Taiwan is not a member of the Madrid System. WIPO Lex’s list of contracting parties to the Madrid Protocol runs to 117 members, and neither Taiwan, Chinese Taipei nor the Republic of China appears on it. Verified against that list on 30 October 2026.
This is not a footnote. It removes an entire layer of docketing machinery that portfolio systems are usually built around, and it removes some risk along with it.
No designation. You cannot reach Taiwan by designating it in an international registration. Every Taiwanese mark in your portfolio is a national filing made directly at TIPO, on its own calendar, with its own publication date.
No central renewal. Renewing an international registration at WIPO does nothing for Taiwan. If a client’s renewal budget is organised around one WIPO renewal covering twenty territories, Taiwan sits outside it and needs its own Article 34 diary entry. This is the most common way a Taiwanese mark lapses in an otherwise well-run portfolio.
No five-year dependency, and no transformation. Under Article 6(3) of the Protocol an international registration stays dependent on the basic mark for five years from the date of the international registration; if the basic mark ceases to have effect in that window the international registration is cancelled to the same extent, with Article 9quinquies transformation as the mitigation. See WIPO’s Guide to the Madrid System. None of that exposure or that remedy touches a Taiwanese registration — it is independent from day one.
And no Section 66(a) analogue. The special US clocks that apply to Madrid-based filings have no Taiwanese counterpart, because there are no Madrid-based Taiwanese filings.
The asymmetry worth docketing is with the mainland. China is a Madrid member and Taiwan is not, so a single brand covering both will have one record reachable centrally and one that never is. Our China trademark docketing deadlines guide covers the CNIPA side, and which countries the Madrid Protocol actually covers lists the other notable absentees.
Article 48: Opposition Runs After Registration, Not Before
Here Taiwan inverts the sequence a US-trained docket expects. Under Article 48, once a mark is registered and published in the Trademark Gazette, any person may file an opposition with TIPO within three months from the date of publication of registration.
Taiwanese opposition is therefore post-registration. The mark is on the register and enforceable while the opposition window is open and while any opposition is being decided.
The US model is the opposite: publication for opposition comes before registration, the initial window is 30 days from publication in the Official Gazette, and extensions of time to oppose are available on request. A docket built on that model has an “opposition period” field positioned at the wrong point in the lifecycle for Taiwan, and an extension concept that does not transfer.
Two consequences for Taiwan trademark docketing. First, the same publication date starts two clocks at once — the ten-year term under Article 33 and the three-month opposition window under Article 48 — so that one date must be captured accurately or both are wrong. Second, a Taiwanese registration is not safe simply because it has registered; a watch service needs to keep looking for three months after the good news arrives.
Our trademark opposition docketing guide covers how to hold pre-registration and post-registration opposition regimes in the same system without collapsing them into one field.
Article 63: The Three-Year Non-Use Clock
Taiwanese non-use exposure arrives sooner than US practitioners expect. Under Article 63(1)(2), a registration is liable to revocation where the mark has not been used for three years after registration, or where use has been suspended for a continuous period of more than three years, without proper reason for non-use.
Three years, not five. The United States places its first compulsory use checkpoint in the fifth-to-sixth year window, and five years of continuous use is also the threshold for incontestability. Taiwan has no compulsory use filing at all — and yet its vulnerability window opens two years earlier than the American one.
That combination is a trap specific to this jurisdiction: no filing obligation to force a use review, and an earlier attack window. Nothing in the Taiwanese procedural calendar will prompt anyone to go and look.
The docketing answer is to create the prompt yourself. Set a diary event at the third anniversary of publication of registration whose purpose is evidence, not filing — confirm the mark is in use in Taiwan on the registered goods or services, and capture dated specimens while they still exist. Repeat it, because the Article also reaches a later three-year suspension of use, not only an initial failure to start.
Our statement of use deadline docketing guide covers the US filing-driven model for comparison; the Taiwanese task is the same evidence discipline with no filing to hang it on.
Articles 57 and 58: The Five-Year Bar and the Three-Year Use Proof
Invalidation in Taiwan carries two time limits that cut in opposite directions, and both belong on a docket because both can expire while nobody is watching.
The five-year bar. Invalidation founded on descriptiveness, lack of distinctiveness, or relative grounds such as similarity to an earlier mark cannot be brought against a mark that has been registered for more than five years. For the owner of a Taiwanese registration this is a date to celebrate — a defensive milestone worth recording, in the way US practitioners record a Section 15 filing.
The three-year use proof. Article 57 requires a party invalidating on the basis of Subparagraph 10 of Paragraph 1 of Article 30 — similarity to an earlier registered mark — to furnish proof that the earlier mark was used, in connection with the registered goods or services, during the three years preceding the invalidation application.
Read that from the attacking side and it is a deadline on your own evidence. The right to rely on your senior Taiwanese registration to knock out a junior one depends on three years of use you can document at the moment you file. A senior registration parked unused is not a usable weapon in Taiwan, however senior it is.
So the third-anniversary use review from the previous section is doing double duty. It defends against Article 63 revocation and it preserves the Article 57 standing you would need to attack. One diary event, two purposes, and the evidence is only gatherable while it is current.
Article 20 Priority: Six Months, WTO Members Only
Taiwan is not a party to the Paris Convention, which follows from its position outside WIPO. Priority is instead granted under Article 20 of the Trademark Act on a reciprocity-or-WTO basis: an applicant who has duly filed in a country with reciprocal recognition of priority rights with the ROC, or with a member of the World Trade Organization, may claim priority within six months from the day following the date of filing of the first such application.
Taiwan acceded to the WTO in 2002, and in practice there are no reciprocity arrangements with states that are not also WTO members. The working rule is therefore that the first filing must have been made in a WTO member for the priority claim to stand.
That is a validation rule, not merely a date. A docket that accepts any foreign first filing as a valid priority basis for Taiwan will occasionally carry a priority claim that cannot be sustained. The basis country needs checking against WTO membership at the point the claim is entered.
Two filing-side deadlines sit alongside it. Where the certified priority document is not filed with the application, it must generally be submitted within three months from the day following the Taiwanese filing date. A simply signed power of attorney is likewise commonly due within three months of filing.
Both are short, both are extendable in principle under Enforcement Rule 8 — unlike renewal — and both are the kind of formality deadline that goes missing when a file is handed between an instructing firm and a local agent.
TIPO Office Action and Appeal Windows
Response periods at TIPO are differentiated by where the applicant sits, which is unusual and easy to mis-model as a single rule.
Reported practice is that a domestic applicant has one month to respond to an examiner’s notice, extendable by a further month, while a foreign applicant has two months, extendable by a further two. Where an application is disapproved, an administrative appeal is due within 30 days following receipt of the decision.
The extension in each case is the general Enforcement Rule 8 power, which requires a reasoned request filed before the original period expires. That is a procedural requirement worth encoding: an extension requested on the day after expiry is not a late extension, it is no extension.
Examination itself typically runs several months from filing to decision, and published estimates vary. Treat pendency as a planning input rather than a docketed deadline, and docket only the periods the statute and Rules actually create.
The 30-day appeal window deserves separate handling. It is the shortest clock in Taiwanese trademark practice, it is counted in days rather than months, and it runs from receipt. A system that normalises every Taiwanese period into months will round it wrongly.
Taiwan vs United States: The Comparison Table the Guides Omit
Most readers looking for Taiwanese deadlines already run a US docket and need to know which of their habits transfer. The ranking guides for Taiwan state Taiwanese dates in isolation; none sets them against the US clocks a practitioner is actually docketing against. Here is that table. US figures are from USPTO’s maintenance guidance and the Federal Register documents cited below.
| Clock | Taiwan (TIPO) | United States (USPTO) |
|---|---|---|
| Term anchor | 10 years from publication of registration (Art. 33) | 10 years from the registration date |
| Who controls the anchor | Partly the applicant — publication follows fee payment (Art. 32) | The Office alone |
| Renewal window | 6 months before expiry; 6 months after at double fee (Art. 34) | Years 9–10 after registration, then every 10 years; 6-month grace |
| Renewal extendable? | No — Art. 34 is carved out of Enforcement Rule 8 | No; grace period only |
| Compulsory use filing | None | §8 declaration in years 5–6, again in years 9–10, then every 10 years |
| Non-use vulnerability | 3 years from registration, or 3 years’ suspension (Art. 63) | 3 years’ non-use raises a presumption of abandonment |
| Incontestability equivalent | No equivalent filing; 5-year bar on certain invalidations (Art. 58) | §15 affidavit — Principal Register plus 5 years’ continuous use |
| Opposition timing | After registration — 3 months from publication of registration (Art. 48) | Before registration — 30 days from publication, extensions available |
| Examination response | 2 months for foreign applicants, extendable by 2 (Rule 8) | 3 months, one 3-month extension (§1/§44); 6 months, no extension (§66(a)) |
| Appeal of refusal | Administrative appeal within 30 days of receipt | TTAB appeal within the response period |
| Priority | 6 months, WTO members or reciprocity (Art. 20) | 6 months, Paris Convention |
| Madrid route | Unavailable — not a Madrid member | §66(a) extensions of protection; §71 affidavits |
| Madrid dependency | Not applicable | 5 years from the international registration date (Protocol Art. 6(3)) |
Four rows in that table are where cross-border dockets actually break: the anchor row, the renewal-extendability row, the opposition-timing row, and the Madrid row. Each one is a case where the US habit is not merely different but produces a confidently wrong date.
The US Office-Action Clocks, Stated Precisely
Because the table above compresses them, the US response periods are worth setting out properly. Practitioners comparing jurisdictions are poorly served by the common shorthand that US office actions are “three months, extendable to six,” because that is true of only one of several clocks.
Examination, Section 1 and/or Section 44 basis. Three months from the issue date, with one three-month extension available. The extension must be requested, with its fee, on or before the end of the initial three months. The Trademark Modernization Act final rule at 86 FR 64300 created the period and a later Federal Register document set its effective date of 3 December 2022 for applications.
Examination, Section 66(a) basis. Six months, with no extension. The rule says expressly that the deadline for responses to office actions in Section 66(a) applications was not changed and remains at six months.
Post-registration office actions. The later of six months, or the end of the one-year period for filing the relevant maintenance document. The three-plus-three window was announced for post-registration office actions, postponed repeatedly, and never came into effect — the Federal Register notice records that the provisions “have never come into effect, and the USPTO has never implemented them.”
That last point is the one most often stated wrongly in published deadline tables, and it is the kind of error that reaches a client as a diary date. Taiwan has no post-registration office-action equivalent at all, since it imposes no maintenance filings — so for a Taiwanese record the question simply does not arise.
The Eight Dates a Taiwanese Record Must Store
Collecting the above into fields. These are the eight dates Taiwan trademark docketing needs to hold separately — not derived from one another — with the Article that creates each and whether a miss is curable.
1. Filing date (Art. 19). Needed for the priority window and for the formality deadlines that run from filing. Not the term anchor.
2. Priority date and basis country (Art. 20). Six months from the day following the first filing, valid only on a WTO-member or reciprocity basis. Store the basis country so the claim can be validated, not just the date.
3. Date of service of the approval decision on the agent (Art. 32). The trigger for the two-month fee clock. Store the service date, never the date the report reached the instructing firm.
4. Registration fee due date — two months, effectively uncurable. The Article 32(3) double-fee route exists but is conditional on third-party rights, so it cannot be relied on as a grace period.
5. Publication of registration date (Art. 33). The term anchor, and the start of the opposition window. Populate it from the Gazette. Everything downstream is wrong if this is estimated.
6. Opposition expiry — three months from publication (Art. 48). After registration, not before. The matter is not closed when the certificate arrives.
7. Third-anniversary use review (Arts. 57 and 63). No filing is due. The event exists to capture dated use evidence, which defends against revocation and preserves invalidation standing.
8. Renewal due date — six months before expiry, not extendable (Art. 34). Plus the six-month double-fee window after expiry, which unlike the fee cure carries no third-party proviso.
A ninth entry is worth adding for the owner’s benefit rather than as a deadline: the fifth anniversary of registration, after which certain invalidation grounds are barred under Article 58.
Our trademark docketing checklist sets out the field-level discipline this assumes, and trademark renewal management covers running these alongside jurisdictions whose anchors disagree.
Where the Ranking Guides Fall Short on Taiwan
Being specific about this is more useful than a general complaint, so here is what the currently-ranking Taiwanese deadline guides do and do not cover. They are written by competent practitioners and their headline figures are right.
What they get right. The ten-year term, the six-month renewal window and six-month grace at double fee, the three-month opposition period, the three-year non-use period, the two-month registration fee, the three-month priority document deadline, and the differentiated office-action response periods. On the facts they state, they are reliable.
Where the anchor goes soft. Several render Article 33 as “ten years from the date of registration.” The statute says publication of registration. In the ordinary case the two coincide closely; in the late-payment case they do not, and that is the case a docket is for.
What is omitted. None of them connects Article 32 to Article 33 — that the applicant’s own payment timing moves the renewal anchor. None mentions the Article 32(3) third-party carve-out, so the fee deadline reads as curable when it may not be. None mentions that Enforcement Rule 8 excludes Article 34 from the extension power. One omits Madrid availability for Taiwan entirely, which is the fact with the largest portfolio consequence.
And none compares. The reader arriving at these pages is usually docketing Taiwan alongside the United States and wants to know which US assumptions survive the trip. That table did not exist on the first page of results for Taiwanese trademark deadlines, which is why it is in this guide.
Nothing here is a claim about any provider’s software, pricing, or reliability. It is a claim about which Articles a published deadline summary addresses, which anyone can check against the statute linked throughout.
A Taiwan Trademark Docketing Audit You Can Run Today
If you already hold Taiwanese registrations in a system built for US anchors, four checks will find most of the damage. Each is a single query.
Check one — the anchor. For every Taiwanese record, compare the stored expiry date against the publication of registration date. Any record where expiry sits exactly ten years after some other date — filing, approval, certificate issue — is suspect, and the direction of the error tells you which field was used.
Check two — the Madrid flag. Query for any Taiwanese record linked to an international registration number, or inheriting a renewal date from one. There should be none. Anything that comes back is a mark whose renewal is being tracked by a WIPO calendar that does not cover it.
Check three — the opposition field. Look for Taiwanese records whose opposition period is stored as closing before the registration date. That ordering is correct for the United States and impossible for Taiwan, and it indicates the field was populated by a US-shaped rule.
Check four — the three-year review. Count Taiwanese registrations more than three years past publication with no use evidence on file. Those are exposed under Article 63 and cannot support an Article 57 invalidation, and because Taiwan demands no maintenance filing, nothing in the docket has ever asked the question.
Whether the checks are run in-house or handed to a managed trademark docketing provider matters less than that someone runs them against the Articles rather than against a generic renewal rule. Taiwan is a jurisdiction where the generic rule is confidently wrong.
Each check either returns nothing, which is reassuring and cheap, or returns a list that needs working through. Our trademark docket audit guide covers running this at portfolio scale, and the Japan and Korea guides cover the two neighbouring regimes most often held in the same database as Taiwan — both of which, unlike Taiwan, are reachable through Madrid.
How PerspireIP Can Help
PerspireIP runs trademark docketing as a managed service for firms and in-house teams whose portfolios cross TIPO, the USPTO, the EUIPO and WIPO. For Taiwanese matters that means the publication-of-registration date is captured from the Trademark Gazette as a first-class field rather than derived from the filing or certificate date, the agent service date is docketed as the trigger for the two-month fee clock, and Taiwanese records are flagged as outside the Madrid System so no WIPO renewal calendar is ever assumed to cover them.
If you hold Taiwanese registrations in a system built for US anchors, the single most useful check is to compare each stored expiry date against the publication of registration date rather than any other date on the record. Any expiry sitting ten years after filing, approval or certificate issue is wrong, and it is a one-query test. We will tell you what we find either way.
Frequently Asked Questions
How long does a Taiwanese trademark registration last?
Ten years from the date of publication for registration, under Article 33 of the Trademark Act, renewable for further ten-year periods. The anchor is publication of registration — not the filing date, and not the date of the approval decision. Because publication follows payment of the registration fee under Article 32, the date the fee is paid feeds forward into every renewal for the life of the mark.
When must the Taiwanese registration fee be paid?
Within two months from the day following the date of service of the approval decision (Article 32). For a foreign holder the clock runs from service on the Taiwanese agent, not from the day the instructing firm read the report. Article 32(3) allows double payment within a further six months where the failure was unintentional — but not where that would affect an application filed or rights obtained by a third party in the interval, so it is not a dependable grace period.
What is the renewal window for a Taiwanese trademark?
Article 34 gives a six-month window before expiry at the standard fee, and a further six months from the day following expiry at double the fee. Renewal may cover all or some of the designated goods or services. No declaration or evidence of use is required to renew in Taiwan.
Can TIPO extend the renewal deadline?
No. Article 8 of the Enforcement Rules of the Trademark Act grants a general power to extend statutory periods on a reasoned request filed before expiry, and it carves out Article 34 by name. Renewal is the one period that cannot be extended on request, which inverts the usual assumption that renewal deadlines are the soft ones.
Is Taiwan a member of the Madrid Protocol?
No. WIPO Lex’s list of contracting parties to the Madrid Protocol runs to 117 members and Taiwan, Chinese Taipei and the Republic of China appear nowhere on it, verified 30 October 2026. Taiwan cannot be designated in an international registration, there is no central renewal covering it, and the Protocol’s five-year dependency and transformation provisions do not apply. Every Taiwanese mark is a national filing on its own calendar.
When can a Taiwanese trademark be opposed?
Within three months from the date of publication of registration, under Article 48. Taiwanese opposition is post-registration, which reverses the US sequence where publication for opposition precedes registration and the initial window is 30 days with extensions available. A Taiwanese mark is not settled simply because it has registered.
How long before a Taiwanese registration is vulnerable for non-use?
Three years. Article 63(1)(2) permits revocation where the mark has not been used for three years after registration, or where use has been suspended for a continuous period of more than three years, without proper reason. That is two years earlier than the US Section 8 checkpoint, and Taiwan imposes no maintenance filing that would prompt a use review — so the prompt has to come from the docket.
Is there a deadline on invalidating a Taiwanese registration?
Yes, in two directions. Invalidation on descriptiveness, lack of distinctiveness or relative grounds such as similarity to an earlier mark cannot be brought against a mark registered for more than five years. And under Article 57, a party invalidating on the basis of similarity to an earlier registered mark must prove that earlier mark was used during the three years preceding the invalidation application.
How does priority work for a Taiwanese trademark application?
Taiwan is outside the Paris Convention, so priority runs under Article 20 of the Trademark Act: six months from the day following the first filing, where that filing was made in a WTO member or in a country with reciprocal recognition of priority with the ROC. In practice there are no reciprocity arrangements with non-WTO states, so the basis country should be validated against WTO membership. A certified priority document is generally due within three months of the Taiwanese filing date.
How long is the response period for a TIPO office action?
Reported practice differentiates by applicant location: one month for domestic applicants, extendable by a further month, and two months for foreign applicants, extendable by a further two. The extension is the general Enforcement Rule 8 power, so the request must be filed before the original period expires. An administrative appeal against a disapproval is due within 30 days of receipt — the shortest clock in Taiwanese trademark practice, and the only one counted in days.
What does Taiwan trademark docketing need that a US-built system does not have?
Four fields and one habit. A publication-of-registration date populated from the Gazette rather than derived; a service date for the approval decision, because the two-month fee clock runs from service on the agent; an opposition window positioned after registration rather than before; and a third-anniversary use review that produces evidence rather than a filing. The habit is never letting a Taiwanese record inherit a renewal date from an international registration, because none covers Taiwan.
