Prior Art Litigation Search in Valencia.

A prior art search Valencia litigation counsel can rely on has to be built for the way Spain actually enforces patents — nationally, before a specialised commercial court, and entirely outside the Unified Patent Court. Valencia is the industrial anchor of Spain’s east coast, a base for the Castellón ceramic-tile cluster, a deep agrifood economy and the automotive plant at Ford Almussafes. When those portfolios are asserted, the validity fight is heard by a designated Spanish judge under national law — not by an international court in Munich or Paris. Barcelona remains the country’s preferred and most experienced patent venue, but a defendant based in the Valencian Community is usually sued at home. PerspireIP builds invalidity-grade searches for the parties challenging those patents before the Valencia commercial court, the OEPM and the EPO.

Where a prior art search Valencia case is actually heard

Spanish patent litigation is not spread across every court in the country. Under a designation by the General Council of the Judiciary (Consejo General del Poder Judicial), patent claims are concentrated in a small number of specialised commercial courts (juzgados de lo mercantil). In the Valencian Community, that competence sits with Commercial Court No. 2 of Valencia, which holds exclusive jurisdiction over patent matters for the whole autonomous community. Design and trademark disputes are routed to Valencia’s Commercial Courts 1 and 3, but a patent infringement or nullity action lands specifically on Court No. 2.

That specialisation is relatively recent. Patent competence was concentrated in Barcelona, Madrid and Valencia after the General Council of the Judiciary’s 2016 agreement, aligned with the Patent Act that took effect on 1 April 2017. Barcelona is the country’s preferred forum for many patentees — its judges are the most experienced and its case management the most predictable — while Valencia’s Court No. 2 hears the disputes anchored to the region’s own industries. Which venue a case lands in shapes timing and tactics, but not the underlying search: a Spanish judge decides novelty and inventive step on the prior art in front of them.

• Commercial Court No. 2, Valencia — the juzgado de lo mercantil with exclusive patent competence for the Valencian Community
• Barcelona (Commercial Courts 1, 4 and 5) — the preferred, most experienced Spanish patent venue
• Venue follows the defendant — a company based in the Valencian Community is usually sued at its own domicile in Valencia
• No bifurcation — the same court decides infringement and validity together, unlike Germany

Spain sits outside the Unified Patent Court

This is the single fact that most distinguishes a Valencia patent dispute from one in Germany, France or the Netherlands. Spain never joined the unitary patent package — it did not enter the enhanced cooperation behind the Unitary Patent and did not sign the Agreement on a Unified Patent Court. The UPC has no jurisdiction over patents in Spain, and no unitary patent takes effect here. A European patent is only enforceable in Spain once it has been validated at the OEPM, which requires a translation of the specification into Spanish.

The consequence for invalidity strategy is direct. A European patent validated in Spain is litigated nationally, before the Valencia commercial court or another designated venue, under the Spanish Patent Act — not before a UPC central or local division. There is no opt-out to weigh and no unitary revocation to file, because neither the unitary patent nor the UPC reaches Spain. Prior art scoped for a Spanish nullity action, and for EPO opposition where the patent has a European parent, is what actually decides the case here.

That national character also means a patentee running a pan-European campaign has to fight Spain separately. A win or loss at the UPC does not bind a Valencia judge, so the Spanish front is a distinct battle — one where locally scoped, Spanish-language-ready prior art gives the accused party its own path to invalidity, independent of whatever is happening in the unitary system. For a Valencian manufacturer facing a European patent, that separate front can be the decisive one.

Nullity under Spain’s 2015 Patent Act

Spanish patent validity is governed by Law 24/2015 on Patents (Ley 24/2015, de 24 de julio, de Patentes), which came fully into force on 1 April 2017 and replaced the 1986 statute. The Act made a decisive change: every Spanish national patent is now granted only after a substantive examination of novelty and inventive step at the OEPM, ending the old optional, largely unexamined route. Patents granted under the current law carry an examiner’s search behind them — but many patents still in force, and every pre-2017 right, do not.

Nullity is codified in Article 102 of the Act. A patent can be declared null where its subject-matter does not meet the patentability requirements — principally novelty, inventive step or industrial applicability; where the specification does not disclose the invention clearly and completely enough to be carried out; where the granted claims extend beyond the application as filed; where the protection was impermissibly broadened after grant; or where the proprietor was not entitled to the patent. Novelty and inventive step are the grounds that turn on prior art, and they are where an invalidity search does its work.

Critically, Spain does not bifurcate. An accused party sued for infringement raises invalidity by counterclaim or defence in the same proceeding, and the commercial court rules on validity and infringement together in a single judgment. When nullity is pleaded by counterclaim, the patentee is given time to respond and may seek to limit the claims. That single-forum structure means the invalidity search cannot be an afterthought: the art you bring is the art the judge weighs against the asserted claims at trial.

• Lack of novelty — a single earlier disclosure that anticipates the claim
• Lack of inventive step — obviousness over the prior art, often a combination of references
• Insufficiency — the specification does not enable the skilled person to work the invention
• Added matter — the granted claims reach beyond the application as filed, or protection was broadened after grant
• Entitlement — the proprietor is not the person entitled to the patent

Ceramics and tile: the Castellon cluster’s patent front

No industry shapes a Valencia prior art search Valencia teams commission more than ceramics. The province of Castellón, just north of the city, is Europe’s densest ceramic-tile cluster — it produces the overwhelming majority of Spain’s tiles and concentrates most of the sector’s companies, alongside the machinery makers and the frit and glaze producers that supply them. The tile sector accounts for close to a fifth of the Valencian region’s industrial output, so when a tile, glaze or process patent is asserted, the accused party is very often a Valencian-Community manufacturer sued at home.

The patents that get asserted here are unusually process-heavy. Digital inkjet decoration, frit and glaze chemistry, large-format and technical porcelain bodies, firing and kiln technology, and surface treatments all generate claims, and the industry’s synergy between tile makers and glaze houses means the same technology is worked by many firms at once. A single assertion can therefore expose a whole tier of Castellón suppliers, each of whom needs to show the claimed method or composition was already old at the priority date.

For an accused ceramics manufacturer the decisive art rarely sits in the patent literature alone. Much of it lives in trade-fair disclosures such as Cevisama, ceramics and materials journals, standards and technical bulletins, older product catalogues, and the sector’s own conference proceedings — grey literature the examiner never saw. A prior art search built for a Castellón tile dispute has to mine those sources and date every reference to the day, so the Valencia court sees a disclosure the patentee’s examiner did not.

Agrifood and automotive: Valencia’s other patent battlegrounds

Beyond ceramics, the Valencian economy is built on agrifood and automotive engineering, and both generate their own patent disputes. The region is Spain’s citrus heartland, and its fast-moving consumer-goods base — anchored by Mercadona, headquartered in the Valencia area — drives demand for packaging, processing, preservation and food-technology inventions. Automotive weight sits at Ford’s plant in Almussafes, one of the company’s major European sites, surrounded by a deep tier of component and tooling suppliers.

The subject-matter differs sharply between the two. Agrifood assertions reach into food processing and packaging machinery, controlled-atmosphere storage, citrus handling and sorting, and formulation, where the decisive reference is often an equipment datasheet, a trade catalogue or a food-science paper. Automotive assertions turn on powertrain and electrification components, materials, driver-assistance and manufacturing methods, where the strongest art frequently sits in engineering standards, SAE and ISO papers, and supplier technical bulletins.

What unites them is the evidentiary problem. In both sectors, and in the region’s furniture and toy industries too, much of the invalidating disclosure is non-patent literature whose publication date is the hardest-fought issue. For a Valencian food processor, a component supplier at Almussafes, or a consumer-goods manufacturer facing an assertion, the durable answer is nearly always a piece of dated, on-point prior art the patentee’s own examiner never reviewed.

Two opposition routes: the OEPM and the nine-month EPO window

Alongside the courts, Spain offers administrative attacks on a patent, and the right one depends on where the patent came from. For a Spanish national patent granted under Law 24/2015, third parties can file an opposition at the OEPM within six months of grant — a post-grant procedure modelled on the European system. It puts novelty and inventive step before the office that granted the patent, without the cost and exposure of a full court action in Valencia.

For the many valuable patents asserted in the region that arrive as European patents validated in Spain, the more powerful route is EPO opposition, filed within nine months of grant. A successful EPO opposition revokes the patent centrally in every state where it was validated, Spain included, in a single proceeding on the same novelty, inventive-step, added-matter and sufficiency grounds a Spanish court would apply. Because Spain cannot use the UPC, the EPO is the one genuinely central forum available for a Spanish dispute.

Both windows close hard. Once the OEPM’s six months or the EPO’s nine months have passed, the accused party is left with national nullity before the Valencia commercial court or another designated venue. Where a window is still open, opposition and national nullity are partners rather than rivals: one rigorous prior art search, charted claim by claim, can feed an opposition and a court action at once, so the same references do double duty. That is why we treat the grant date of any asserted patent as a hard diary entry the moment we are instructed.

How PerspireIP builds a Valencia invalidity search

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 printed on the cover. For ceramics assertions we run patent searching alongside deep non-patent retrieval — frit and glaze chemistry, materials and ceramics journals, Cevisama and trade-fair disclosures, machinery catalogues and technical bulletins. For agrifood and automotive claims we reach food-science and engineering literature, standards, datasheets and archived product documentation, dating every reference to the day.

• Claim charting mapped to novelty and inventive step under Article 102 of Law 24/2015 and the EPC
• Deep non-patent retrieval across ceramics, materials, food-science, standards and grey-literature sources, in Spanish and other languages
• Public-availability dating for every reference, evidenced for journals, trade-fair disclosures and online sources alike
• Prior art scoped to your forum — a Valencia commercial-court nullity counterclaim, an OEPM opposition, or the nine-month EPO window
• Search results and disclosures readied for use in Spanish proceedings, translation-friendly for validated European patents

We work alongside your Spanish and European counsel as a specialist search partner, deliver to court and opposition deadlines, and keep every engagement confidential. Whether you are a Castellón tile or glaze maker, a Valencian food processor, an automotive supplier at Almussafes, or litigation counsel preparing a nullity defence, we scale to fit — a single search, a multi-patent campaign, or ongoing portfolio support. Because Spain is litigated nationally and outside the UPC, a prior art search Valencia teams commission has to stand on Spanish law and its own evidence. Send us the patent number and your key dates, and we will scope the work within one business day.
