Patent Invalidation in Valencia.

A patent invalidation Valencia strategy starts from a fact most foreign counsel miss: Valencia is not a second-tier venue but one of only three cities in Spain with a specialized patent court. Spain sits inside the European Patent Convention yet outside the Unified Patent Court, so a European patent is enforced — and knocked out — nationally here, under Spanish law, in the Juzgado de lo Mercantil nº 2 de Valencia that holds exclusive patent jurisdiction for the whole Valencian Community. Since the Patents Act 24/2015 came into force on 1 April 2017, an accused party also has an administrative alternative before the OEPM (Oficina Española de Patentes y Marcas). PerspireIP builds invalidity-grade prior-art searches for the manufacturers, importers and competitors who have to defeat a patent or a utility model in Valencia’s ceramics, agrifood and automotive economy.

Why patent invalidation Valencia cases stay national and local

Spain ratified the European Patent Convention but never joined the Unified Patent Court, and it has no plans to. That single choice defines a patent invalidation Valencia case. A European patent validated for Spain does not fall under any Luxembourg-supervised UPC division; it can only be revoked here, on Spanish soil, under the Patents Act 24/2015 (Ley 24/2015, de 24 de julio, de Patentes). For a company sued in Valencia, there is no pan-European shortcut and no central revocation button — the Spanish designation lives or dies by Spanish rules.

What surprises foreign litigants is the venue. Patent disputes in Spain are concentrated in a handful of specialized commercial courts, and Valencia is one of only three seats — alongside Barcelona and Madrid — that the General Council of the Judiciary designated to hear patent matters exclusively. So a defendant in Alicante, Castellón or the city of Valencia does not travel to Barcelona by default; the local specialized court has full jurisdiction over validity and infringement alike.

That gives the accused two distinct battlefields. Validity can be fought in court — as a standalone nullity action or as a counterclaim inside an infringement suit — or, for some purposes, administratively before the OEPM. Whichever route is chosen, the case turns on prior art, because Spanish judges and OEPM examiners apply the same substantive tests of novelty and inventive step the European Patent Office uses. Getting the art right, and provably dated, is the whole game.

Valencia: one of only three specialized patent courts in Spain

Under Article 118 of the Patents Act, the General Council of the Judiciary (Consejo General del Poder Judicial) may concentrate patent jurisdiction in the commercial court of a city that seats a High Court of Justice. Its first agreements, adopted in December 2016 and February 2017, named three regions with the heaviest patent workload: Catalonia (Barcelona), Madrid and the Valencian Community. In Valencia, the Juzgado de lo Mercantil nº 2 hears patents exclusively, while the region’s other commercial courts keep trademarks and industrial designs.

This is a real strategic asset for the accused. A Valencian manufacturer facing an infringement claim does not have to litigate validity in a distant forum; a specialized judge who reads patents daily sits in the same autonomous community. Barcelona remains the venue foreign patentees reach for out of habit, but a defendant with a strong invalidity case has a genuine argument to keep the fight in Valencia, closer to its evidence, its witnesses and its industry.

There is one more wrinkle worth knowing. Since 14 January 2023, Spain moved trademark and trade-name nullity and revocation out of the courts and into the OEPM. Patents were left untouched. So while a competitor can cancel a Valencian trademark administratively, third-party patent nullity still runs through the commercial court — another reason the Juzgado de lo Mercantil nº 2 de Valencia matters, and why the search you bring to it has to survive judicial scrutiny.

The OEPM alternative: post-grant opposition, revocation and limitation

The Patents Act 24/2015 opened an administrative track that the old 1986 law did not offer. Under the previous regime, opposition to a Spanish patent was filed before grant; today, any third party may oppose a granted patent within six months of the mention of grant in the Official Industrial Property Gazette. That post-grant opposition is decided by the OEPM itself, on grounds of lack of patentability, insufficient disclosure or added matter — the same defects a nullity action raises, but resolved administratively and often faster.

The Act also lets a patent holder move first. A patentee may ask the OEPM to revoke or limit its own patent by amending the claims at any time during the life of the right, and may limit the patent inside litigation where its validity is under attack. These revocations and limitations take retroactive effect. For a defendant, that means the claim set you are attacking can shrink under pressure, so an invalidity search has to anticipate the narrower fallback claims a patentee will retreat to.

For European patents validated in Spain, a further route runs through the EPO: a centralized opposition within nine months of grant that, if successful, wipes out the Spanish designation without a Valencian courtroom ever being involved. Coordinating an EPO opposition, an OEPM post-grant opposition and a possible national nullity action — and picking the right one for the timeline — is a decision that should be made on the strength of the prior art in hand.

The end of the soft patent: mandatory examination since 2017

The most consequential change for validity work is quiet but sweeping. The old Patents Act of 1986 let applicants choose whether their Spanish patent underwent substantive examination — a system nicknamed the patent ‘a la carta’. Many rights were granted without any real check on novelty or inventive step, producing a stock of weak patents that shifted the cost and burden of clean-up onto competitors, who had to litigate to annul rights that should never have issued.

The Patents Act 24/2015 ended that. From 1 April 2017, substantive examination of novelty and inventive step became mandatory for every Spanish patent, aligning the OEPM with EPO practice and strengthening legal certainty. New grants are meaningfully harder to invalidate because an examiner has already tested them against the art.

But the transitional reality is a gift to defendants. Patents filed under the old regime run for twenty years, so soft, un-examined rights granted before the switch are still being enforced across Valencia’s traditional industries today. These are exactly the patents a rigorous prior-art search exposes, because no examiner ever searched them properly. Knowing which statute governed a patent’s grant is an early strategic question in every Valencian matter, and it often points straight at the weakest link.

Utility models: Valencia’s overlooked invalidity battleground

Valencia’s economy is built on incremental mechanical and materials innovation — tile presses and glaze formulations, furniture fittings, irrigation and packing-house equipment, automotive components. Industries like these lean heavily on the utility model (modelo de utilidad), Spain’s faster, cheaper second-tier right with a lower inventive-step bar than a full patent. If you are cleared or accused in Valencia, the exclusive right blocking you is as likely to be a utility model as a patent.

The Patents Act 24/2015 rewired utility models, and every change cuts in the defendant’s favour. Novelty is now assessed against the worldwide state of the art, not merely what was known in Spain, so foreign disclosures anticipate a Valencian utility model just as they would a patent. Protection was extended to chemical products and compositions — relevant to frits, enamels and agrifood formulations — while pharmaceutical substances stay excluded.

• Worldwide novelty — any prior disclosure anywhere in the world can now anticipate a utility model, widening the pool of killer art
• Mandatory search report to sue — a holder must obtain or request an OEPM search report on the state of the art before it can enforce a utility model in court
• Broader subject matter — chemical products and compositions are now protectable, except pharmaceutical substances and compositions
• Lower inventive-step threshold — easier to grant, which means the decisive question at trial is almost always the prior art

That search-report requirement is a lever. A utility-model owner cannot press an injunction in Valencia without putting a state-of-the-art report on the table, and that report becomes a target: if our search surfaces closer art than the OEPM found, the right is exposed before the merits are even reached.

Where Valencia’s decisive prior art actually lives

Valencia’s patent docket mirrors its industrial map, and each sector invalidates on different evidence. The Castellón ceramic-tile cluster north of the city produces close to 20% of the region’s industrial GDP and hosts most of Spain’s tile makers, along with the frit, enamel and ceramic-colour suppliers that drive its R&D and its patents, supported by the Instituto de Tecnología Cerámica at the Universitat Jaume I and the ASCER industry body. To the south, the Ford plant at Almussafes anchors a deep automotive-components and furniture supplier base, while Valencia, Castellón and Alicante lead Spain’s citrus and agrifood output.

These are materials and mechanical technologies, and their decisive reference is rarely the first patent a keyword search returns. It usually hides in engineering handbooks, industry standards, trade catalogues, older equipment manuals or Spanish- and other foreign-language literature that an examiner never retrieved — especially for a soft patent or a utility model granted with a thin search.

• Ceramics and materials journals, glaze and frit formulations, and older tile-press and kiln patents for Castellón cluster claims
• ASTM, ISO and UNE standards, machinery manuals and datasheets for manufacturing-process and equipment claims
• Agrifood, irrigation, packaging and cold-chain trade literature and product catalogues for citrus and horticulture claims
• Automotive-component datasheets and supplier documentation tied to the Almussafes ecosystem
• Spanish- and other foreign-language disclosures, theses and abandoned patent families an examiner is unlikely to have found

The other half of the job is proof of date. A reference only counts if it was genuinely public before the priority date the claim relies on. We treat public-availability dating as evidence — capturing print dates, archive timestamps, catalogue records and library holdings that the Juzgado de lo Mercantil nº 2 de Valencia or an OEPM examiner will accept without a side dispute over authenticity.

How PerspireIP builds a patent invalidation Valencia case

Every engagement follows the same disciplined path. We map the asserted claims element by element, fix the priority date that actually governs each one, and search against that date rather than the filing date on the cover. For ceramics, materials, agrifood and mechanical subject matter we run patent and deep non-patent-literature retrieval in parallel, add standards and engineering references, and pull the Spanish- and foreign-language art that national prosecution routinely misses.

• Claim charting mapped to the grounds Spanish courts and the OEPM apply — novelty, inventive step, sufficiency and added matter
• A read on which statute governed grant — the modern 24/2015 examination regime or the old soft-patent system — to find the weakest link
• Parallel patent and non-patent-literature searching tuned to tile, glaze, agrifood, furniture and automotive-component claims
• Utility-model attacks built around worldwide novelty and the holder’s mandatory state-of-the-art report
• Public-availability dating evidenced for every reference, ready for the court record or an OEPM opposition

We work alongside your Spanish patent attorneys and litigators as a specialist search partner, deliver to court and OEPM deadlines, and keep every engagement confidential. Whether you are defending an infringement action before the Juzgado de lo Mercantil nº 2 de Valencia, weighing a post-grant opposition, or clearing a product line into the Castellón or Almussafes supply chain, we scale to fit. Because a patent invalidation Valencia case runs on the strength of the art, send us the patent or utility-model number and your key dates, and we will scope the work within one business day.
