Patent Invalidation in Washington, District of Columbia

Patent invalidation Washington strategy is driven by institutions rather than by one local trial docket. The U.S. International Trade Commission sits at 500 E Street SW; the U.S. Court of Appeals for the Federal Circuit, which hears every U.S. patent appeal in the country, sits in the Howard T. Markey National Courts Building on Madison Place beside Lafayette Square; and the USPTO with its Patent Trial and Appeal Board sits across the Potomac in Alexandria, Virginia. PerspireIP builds invalidity and prior-art records for respondents, petitioners and defendants who have to satisfy all three at once.

Why patent invalidation Washington cases run on the ITC clock

Washington, DC is the institutional capital of United States patent law. Almost nothing about a validity fight here is decided by geography — it is decided by which federal body is holding the pen, and by how little time that body gives you. The U.S. International Trade Commission is the sharpest example. Section 337 declares infringement of a U.S. patent by imported articles to be an unlawful practice, and the Commission investigates it on a schedule that district-court litigators find genuinely disorienting.

By statute the USITC must conclude an investigation at the earliest practicable time, and within 45 days of instituting one it must set a target date for its final determination. The Commission’s own published statistics put the average length of investigations decided on the merits at 16.3 months in fiscal year 2025, with recent years clustering in the 16-to-18-month range. Discovery, expert reports and an evidentiary hearing before an administrative law judge all have to fit inside that window.

For a respondent, the commercial consequence is blunt: the prior-art work that a defendant in a normal patent suit can spread over two or three years has to be finished in a fraction of that time. Invalidity contentions land early, the hearing arrives fast, and there is no realistic opportunity to go back and find the reference you missed. Search quality and search speed stop being separate questions in a Washington ITC matter.

Section 337: an exclusion order, not a damages award

The ITC does not award money. Its remedies are in rem and border-facing: an exclusion order directing U.S. Customs and Border Protection to stop the infringing articles at the border, and cease-and-desist orders directed at named respondents already holding inventory in the United States. A complainant who wants damages must go to a district court; a complainant who wants a respondent’s product off the U.S. market goes to the ITC. That is why Section 337 is used as leverage.

The procedure has two tiers. An administrative law judge presides over the evidentiary hearing and issues an initial determination on all issues related to a violation of Section 337. The Commission may then review and adopt, modify or reverse that decision; if it declines review, the initial determination becomes the Commission’s own. Remedial orders take effect on issuance and become final 60 days later unless disapproved on policy grounds by the U.S. Trade Representative during that Presidential review period.

Because the remedy is exclusion rather than compensation, a respondent cannot price the risk and carry on. Losing means losing access to the U.S. market for the accused articles. Invalidity is therefore not a bargaining chip in a Section 337 investigation — for many respondents it is the whole defence.

The ITC cannot invalidate a patent, but invalidity is a full defence

This distinction trips up companies new to the Commission. The USITC has no power to cancel or invalidate a patent claim; only the USPTO, through the PTAB, or an Article III court can do that. What the Commission can do is find no violation of Section 337 because the asserted claims are invalid. Invalidity is pleaded and tried at the ITC exactly as it would be in court, on anticipation, obviousness, written description, enablement and eligibility grounds.

The corollary matters just as much. Because the Commission’s patent determinations are made for Section 337 purposes only, the Federal Circuit held in Tandon Corp. v. U.S. International Trade Commission, 831 F.2d 1017 (Fed. Cir. 1987), that they should not carry res judicata or collateral estoppel effect in later court proceedings. A win at the ITC does not permanently kill the patent, and a loss there does not formally bind you in a parallel district-court case.

Practically, that pushes sophisticated respondents toward a parallel strategy: defend the Section 337 investigation on invalidity while filing an inter partes review at the PTAB in Alexandria to seek cancellation that actually sticks. Both tracks draw on the same prior art, so the underlying search has to be built once, and built well enough to serve two very different forums.

Domestic industry and the 100-day early disposition off-ramp

Section 337 relief is not available to every patent owner. The complainant must establish a domestic industry in the United States relating to articles protected by the asserted patent. That has two prongs: a technical prong, showing articles that actually practise the intellectual property, and an economic prong, showing significant investment in plant and equipment, significant employment of labour or capital, or substantial investment in exploitation such as engineering, research and development, or licensing.

Domestic industry is one of the most heavily litigated issues at the Commission, and it is a genuine escape route. Under the USITC’s early disposition programme, the Commission can identify at institution an investigation that presents a potentially dispositive issue — domestic industry being the classic one — and direct the ALJ to hold an abbreviated hearing and issue an early initial determination within 100 days.

• Technical-prong analysis: do the complainant’s own articles read on the asserted claims?
• Prior art aimed at the claims the complainant needs for its domestic-industry products
• Invalidity charts built to the ITC’s compressed evidentiary schedule
• A single reference base that also supports a PTAB petition

The technical prong is where invalidity and domestic industry converge: claims construed broadly enough to capture your imports are often broad enough to read on prior art. Our searches are scoped with that squeeze in mind.

Build the record for the Federal Circuit from day one

Every road out of Washington leads to the same courthouse. The U.S. Court of Appeals for the Federal Circuit has exclusive nationwide jurisdiction over patent appeals, and it hears appeals from ITC final determinations, from PTAB final written decisions, and from the Court of Federal Claims. It sits in the Howard T. Markey National Courts Building at 717 Madison Place NW, a short walk from the White House — the same building that houses the Court of Federal Claims.

The standard of review is what should shape your evidence strategy. Reviewing agency decisions, the Federal Circuit takes legal conclusions de novo but reviews factual findings only for substantial evidence. Obviousness is a legal question resting on underlying factual findings; anticipation, written description and the factual predicates of obviousness are reviewed deferentially. In plain terms: a factual finding you lost below is very hard to overturn on appeal.

So a patent invalidation Washington record has to be made at the ALJ hearing or in the PTAB petition, not afterwards. A reference you did not put in front of the fact-finder is a reference the Federal Circuit will not weigh. This is the single strongest argument for front-loading a rigorous, documented, well-authenticated search in any Washington matter — the appellate court reviews the record you built, not the case you wish you had run.

Government contractors, defense and Section 1498 claims

The technology economy around Washington is unlike any other in the United States. Defence primes, aerospace suppliers, cybersecurity firms, systems integrators and govtech companies cluster through the Northern Virginia and Maryland corridor, and a very large share of their revenue comes from federal contracts. That changes the shape of patent exposure.

Under 28 U.S.C. § 1498, where a patented invention is used or manufactured by or for the United States without a licence, the patent owner’s remedy is an action against the United States in the U.S. Court of Federal Claims for reasonable and entire compensation. Use or manufacture by a contractor or subcontractor for the Government, with the Government’s authorisation and consent, counts as use by the United States. The practical effect is that the contractor is not sued directly, and no injunction issues against the Government’s operations.

Compensation is still real money, and validity remains squarely in issue. Because the Court of Federal Claims also sits in the Markey building in Washington and appeals run to the Federal Circuit upstairs, contractors face the same appellate discipline as ITC respondents. Prior art in this space frequently sits in government technical reports, standards bodies, conference proceedings and defence-adjacent literature that ordinary patent-database searching never surfaces.

How PerspireIP scopes an invalidity search in Washington, DC

Every patent invalidation Washington project starts the same way. We map the asserted claims element by element against the accused imports or accused system, then search patent literature and non-patent literature worldwide — journals, standards contributions, product manuals, technical reports, theses and archived product documentation — for anticipation and obviousness references. Every result is charted so your counsel can drop it straight into ITC invalidity contentions, an IPR petition, or a Court of Federal Claims defence.

• Element-by-element claim charts for each candidate reference
• Public-availability and date evidence built to survive cross-examination
• Combination theories with articulated motivation-to-combine support
• A written invalidity opinion memo, plus a deliverable schedule keyed to your target date

Two things distinguish a Washington engagement. First, tempo: we scope against your ITC target date or your PTAB one-year statutory deadline and work backwards, because there is no second bite. Second, authentication: at the Commission and at the Board, a reference is worth nothing until you can prove when and how the public could get it, so we document provenance as we go.

Whether you are a respondent in a Section 337 investigation, an IPR petitioner filing in Alexandria, or a federal contractor defending a § 1498 claim, we work as a specialist search partner alongside your litigation team and to your deadlines.
