Infringement Analysis in Madrid.

A patent infringement analysis Madrid litigators can act on has to reckon with two features that make Spain distinctive — a European patent is enforced here purely as a national right, because Spain has stayed outside the Unified Patent Court, and a single specialised commercial court weighs both infringement and validity in one proceeding. Madrid is Spain’s corporate capital, home to the Spanish Patent and Trademark Office (OEPM) and to the telecoms, banking, energy and pharmaceutical groups whose portfolios drive Spanish patent disputes. The patents asserted here read on network and payment technologies, drug formulations, energy systems and connected devices, and every case turns on whether the accused product actually practises the claim. PerspireIP builds the claim charts and evidence-of-use that prove — or defeat — that link.

Where a patent infringement analysis Madrid case is heard

Patent disputes in Spain are not heard by general civil judges. Under Article 118 of the Spanish Patent Act (Ley 24/2015), objective jurisdiction is reserved for the specialised commercial courts (juzgados de lo mercantil) seated in the cities to which the General Council of the Judiciary has assigned patent matters. Today those courts sit in Barcelona, Madrid and Valencia, with specialised competence extended since 1 January 2019 to Granada, Las Palmas de Gran Canaria, A Coruña and Bilbao. A patent owner can, within limits, choose among these forums, which makes venue a strategic decision from day one.

Honesty about the map matters. Barcelona is Spain’s leading patent venue — its commercial courts numbers 1, 4 and 5 concentrate the deepest technical bench, and the largest share of Spanish patent infringement actions is filed there. Madrid is the country’s corporate and financial capital, and its commercial courts numbers 6 to 11 hold specialised competence over patents, designs and trademarks. Because so many telecoms, banking, energy and pharmaceutical groups are headquartered in Madrid, it is a natural forum for portfolio-driven and headquarters-based disputes, and any analysis prepared for a Madrid matter must be built to the same technical standard the Spanish specialised bench applies everywhere.

• Commercial courts of Madrid (juzgados de lo mercantil, nos. 6–11) — specialised first-instance courts with competence over patent, design and trademark disputes, and a natural venue for Madrid-headquartered rights holders
• Commercial courts of Barcelona (nos. 1, 4 and 5) — Spain’s pre-eminent patent forum, where most national infringement actions are filed
• Provincial Court of Madrid (Audiencia Provincial de Madrid) — the specialised appellate sections that hear appeals against the commercial courts’ first-instance judgments
• OEPM (Spanish Patent and Trademark Office) — the Madrid-seated national office that grants and validates the patents being enforced; a further cassation appeal can reach the Supreme Court (Tribunal Supremo)

Timing shapes how early the analysis has to be ready. A first-instance patent case before the Spanish commercial courts typically runs around 18 to 24 months to judgment, and an appeal to the Provincial Court a further 8 to 15 months. Because the specialised bench expects a technically rigorous claim reading from the complaint onward — and because the most powerful evidence tools are requested before or at the very start of proceedings — the claim chart and evidence-of-use cannot be assembled after filing. They have to be litigation-ready for this bench from the outset, whether the matter is filed in Madrid or in Barcelona.

Spain outside the UPC: European patents enforced nationally

The single fact that reshapes strategy in Madrid is what does not apply. Spain is a founding member of the European Patent Convention, so European patents are granted and validated for Spain — but Spain has not joined the Unified Patent Court and is not part of the Unitary Patent system. It challenged the unitary-patent package before the Court of Justice of the EU, whose judgments in cases C-146/13 and C-147/13 of 5 May 2015 dismissed those actions; Spain nonetheless chose to stay out. No unitary patent takes effect on Spanish territory, no UPC division sits in Spain, and the UPC’s central revocation and pan-European injunction cannot directly govern a Spanish national right.

A European patent therefore reaches Madrid only as a national Spanish right validated before the OEPM, litigated in the Spanish commercial courts under the Patent Act and the Civil Procedure Act. There is no unitary layer to opt into and no UPC route to defend against on Spanish soil. A patentee running one family across Europe cannot fold Spain into a UPC campaign, and a Spanish company cannot be swept into a unitary injunction that automatically reaches Madrid. Spain is a separate national front that must be fought on its own terms.

For an infringement analysis that is decisive. The claim chart and evidence-of-use have to be built to Spanish procedural standards — for a commercial-court complaint and for the Patent Act’s own evidence tools — not for a court with no authority over a Spanish patent. One nuance is worth flagging: recent UPC case law has asserted long-arm jurisdiction over infringing acts in non-contracting states, Spain included, where the defendant is domiciled in a UPC country. That does not make Spain a UPC member or create a Spanish division; for a right validated and enforced in Spain, the national track remains the primary battleground, and the analysis is built to serve it first.

One court, two questions: infringement and validity together

Spain runs a unified system, and this is where it diverges sharply from bifurcated jurisdictions such as Germany or the administrative split used in Poland. The same specialised commercial court that decides infringement also rules on the validity of the patent in the same proceeding. There is no separate office track for invalidation once litigation is under way — the court that hears the infringement claim can revoke the patent itself.

In practice, a defendant sued for infringement will typically respond in one of two ways. It can file a revocation counterclaim in its statement of defence, asking the court to declare the patent invalid with erga omnes effect; or it can raise invalidity merely as a defence, in which case a successful challenge defeats the infringement claim but the patent itself survives, the finding having only inter partes effect. Either route puts validity squarely in front of the same judge who is weighing infringement.

The strategic consequence is that infringement and invalidity cannot be worked up in isolation. A patentee needs a claim chart robust enough to survive a revocation counterclaim decided by the very court hearing the infringement action, and an accused party needs a non-infringement position paired with a credible prior-art invalidity case, both ready for the same courtroom. PerspireIP scopes each analysis knowing that in Spain the two questions are answered together, not on separate clocks.

Ley 24/2015 and the diligencias de comprobación de hechos

The governing statute is the Spanish Patent Act, Ley 24/2015 de Patentes, in force since 1 April 2017 (with its implementing regulation approved by Royal Decree 316/2017). It modernised enforcement and, crucially for an infringement analysis, preserved Spain’s distinctive pre-suit evidence mechanism: the diligencias de comprobación de hechos (fact-verification proceedings), governed by Articles 123 to 126.

These proceedings let a rights holder ask the court to verify, at the alleged infringer’s premises, facts that could not otherwise be established without inspecting a competitor’s products, processes or documents. A defining feature is that the measure is ordered and carried out without prior notice to the party who must bear it, so the inspection is not frustrated by advance warning, while the court builds in safeguards to protect the defendant’s confidential information. It is Spain’s counterpart to the evidence-securing tools used elsewhere in Europe, and it is often the fastest route to proof of infringement that lives behind a factory door.

• Diligencias de comprobación de hechos — ex parte, court-supervised fact verification at the alleged infringer’s premises, granted where there are reasonable indications of infringement (Arts. 123–126)
• Preliminary injunctions and precautionary measures — available to freeze infringing conduct pending judgment
• Final remedies — a permanent injunction, damages, recall and removal from commercial channels, and destruction of infringing goods

Every one of these tools is only as strong as the claim mapping behind it. A judge asked to order a surprise inspection, or to grant an injunction, needs a clear, element-by-element showing of why the accused product plausibly reads on the asserted claim. That mapping is the deliverable, and it has to exist before the measure is even requested.

Madrid’s industries: what the asserted patents claim

Madrid’s litigation profile is written by the industries headquartered around it. The city is the seat of Telefónica, one of the world’s largest telecoms operators, and telecommunications patents — network protocols, signal processing, connectivity and standard-essential technologies — are among the most heavily litigated anywhere. Infringement in these cases is rarely visible on a datasheet; it has to be reconstructed from device behaviour, network traces, technical standards and reverse-engineered functionality, then charted against every limitation of the claim.

Banking and financial services form a second heavy stream. Madrid anchors Santander, BBVA, CaixaBank and Bankinter, and the patents asserted in this cluster read on payment systems, transaction security, authentication and software-driven financial platforms. A third stream flows from Spain’s energy champions — Iberdrola, Endesa, Naturgy and Red Eléctrica — whose portfolios cover grid technology, renewable generation, storage and smart-metering inventions.

Pharmaceuticals complete the picture. Madrid hosts the Spanish operations of numerous multinational drug makers and the industry association Farmaindustria, and pharma is one of the most litigated patent fields in Spain, with a strong domestic generics sector on the other side. The asserted claims read on formulations, salts and polymorphs, dosage regimens and manufacturing processes, and each demands that infringement be proven against a specific marketed product, not asserted in the abstract. Whether the technology is a network protocol, a payment method, a grid system or a polymorph, the commercial question is identical: does the accused product or process actually fall within the scope of the asserted claim?

The pharmaceutical stream deserves a closer look, because Spain’s generics industry makes it one of the busiest corners of the docket. Originators enforce formulation, polymorph, second-medical-use and process patents against generic entrants, while generic manufacturers routinely front-load an invalidity attack, either as a revocation counterclaim or a standalone action, to clear the way to market before a product launch. Proving or defeating infringement here means comparing the accused medicine’s composition, crystalline form or manufacturing route against the claim with laboratory-grade precision, and pairing that reading with a prior-art position that will hold up in the same courtroom. It is a discipline that rewards the element-by-element rigour PerspireIP brings to every chart.

How PerspireIP builds a Madrid infringement-analysis file

Every engagement follows the same disciplined path. We construct the claim scope first, fixing the correct construction from the claims, specification and prosecution history, then map each element against the real accused product or process. For telecoms we work from device behaviour, network analysis and technical standards; for banking and fintech from documented functionality, APIs and system analysis; for energy from equipment teardowns and technical datasheets; and for pharma from formulations, polymorph data and regulatory dossiers — charting infringement literally and, where appropriate, under the doctrine of equivalents.

• Claim construction and element-by-element charting to Spanish Patent Act (Ley 24/2015) and EPC standards
• Evidence-of-use assembly — teardowns, network and software analysis, datasheets, regulatory and public technical sources — dated and documented
• Infringement and non-infringement positions built for either side of a Spanish commercial-court dispute, including a defensive brief against a revocation counterclaim
• Deliverables scoped to Spain’s tools: a first-instance complaint, or the evidence base for a diligencias de comprobación de hechos request or a preliminary injunction
• Coordination with the reality that one court decides both infringement and validity, and that Spain sits entirely outside the UPC and Unitary Patent system

We work alongside your Spanish and European counsel as a specialist analysis partner, deliver to commercial-court and OEPM deadlines, and keep every engagement confidential. Whether you are a telecoms, banking, energy or pharmaceutical company enforcing a patent, an accused party clearing a path to market, or litigation counsel preparing a complaint or a defence, a patent infringement analysis Madrid companies can rely on scales to fit — a single claim chart, a multi-patent matter or ongoing portfolio support. Send us the patent number and the accused product, and we will scope the work within one business day.
