Patent Invalidation in Lausanne.

Patent invalidation Lausanne strategy runs on a Swiss reality most foreign counsel get wrong: Switzerland is a full member of the European Patent Organisation but sits entirely outside the European Union, the Unitary Patent and the Unified Patent Court. A European patent still covers Switzerland — jointly with Liechtenstein as a single territorial unit — yet it is opposed, revoked and enforced under Swiss rules, not through the UPC in Paris or Munich. For a company defending an assertion around Lake Geneva, that means two very Swiss forums: EPO opposition in Munich and The Hague, and the Swiss Federal Patent Court in St. Gallen, with final appeals heard by the Federal Supreme Court right here in Lausanne. PerspireIP builds revocation-grade invalidity searches for the medtech, robotics and life-sciences companies spun out of EPFL and the wider Health Valley.

Why patent invalidation Lausanne strategy starts outside the UPC

The single most important fact for any Lausanne defendant is what Switzerland is not part of. Because Switzerland is not an EU member state, it cannot join the Unitary Patent or the Unified Patent Court, even though it sits alongside the UK and Norway as a European Patent Convention country. A Unitary Patent has no effect in Switzerland, and the UPC has no jurisdiction over a Swiss designation. Anyone treating a Swiss dispute as if the Paris or Munich UPC divisions decide it has already made a costly mistake.

What Switzerland does have is EPO membership, so a European patent granted in Munich still reaches Swiss soil. Uniquely, a European patent can only be granted jointly for Switzerland and Liechtenstein — the two states form a single unitary patent unit under Articles 142 and 149 EPC, the only such unit in force until the EU Unitary Patent arrived in 2023. You cannot invalidate the patent in one country and leave it standing in the other.

• Switzerland is an EPO member but not an EU, Unitary Patent or UPC member
• A European patent covers Switzerland and Liechtenstein jointly as one unit
• The UPC in Paris, Munich and Milan has no jurisdiction over the Swiss designation
• Validity is decided by EPO opposition or the Swiss Federal Patent Court — never the UPC

EPO opposition: the central revocation route for a Lausanne patent

For a European patent asserted in Lausanne, the fastest centralized way to kill it is opposition at the European Patent Office. Any third party may file an opposition within nine months of the mention of grant appearing in the European Patent Bulletin, and a successful opposition revokes the patent centrally — for Switzerland, Liechtenstein and every other designated state at once. That reach is exactly why the nine-month window is the highest-value moment in a European patent’s life.

Opposition grounds are the classic ones: lack of novelty and inventive step, added subject-matter, insufficiency of disclosure and non-patentable subject-matter. Every one of them is won or lost on prior art and its dates. A single dated reference that anticipates the claim, or a two-reference obviousness combination, can revoke a patent that a licensing campaign was built on.

Miss the nine-month window and the centralized route closes — validity then has to be attacked country by country. In Switzerland that means the Federal Patent Court, so a patent invalidation Lausanne plan is really a decision between two forums with very different reach and timing.

The Swiss Federal Patent Court: one national court, technical judges

Since 2012 Switzerland has concentrated all first-instance patent disputes in a single specialised court: the Federal Patent Court (Bundespatentgericht / Tribunal fédéral des brevets), seated in St. Gallen. It has exclusive nationwide jurisdiction over patent validity and infringement, taking over from the 26 cantonal courts that once heard these cases. There is no forum shopping in Switzerland — every nullity action and every infringement suit lands in the same court.

Its defining feature is the bench. Panels combine legally trained judges with technically trained judges — engineers and scientists with proven patent-law knowledge — so a validity argument is read by people who understand the technology. For medtech, robotics and life-sciences claims common around Lausanne, that raises the bar: a superficial prior-art hit list will not survive judges who can read the reference as closely as the specification.

• Federal Patent Court, St. Gallen — exclusive first-instance jurisdiction over validity and infringement
• Operating since 2012, replacing 26 cantonal courts — no forum shopping
• Mixed panels of legally and technically qualified judges
• A nullity action or nullity counterclaim can revoke the Swiss–Liechtenstein designation

Why the Federal Supreme Court in Lausanne is the local hook

Here is where Lausanne stops being a generic address and becomes the centre of Swiss patent law. Appeals from the Federal Patent Court do not go to a regional court — they go to the Swiss Federal Supreme Court (Tribunal fédéral / Bundesgericht), whose seat is in Lausanne. The final word on whether a Swiss patent lives or dies is written a short walk from EPFL and the shores of Lake Geneva.

The appeal is deliberately narrow. The losing party may raise only questions of law; the Federal Supreme Court will not re-examine the Federal Patent Court’s factual findings unless they are obviously wrong, and new evidence is generally not admitted. Appeal proceedings typically run six to eight months. The practical lesson is unforgiving: the prior-art record has to be complete and correctly dated at first instance, because Lausanne is not a place to introduce the reference you should have found earlier.

That is why a patent invalidation Lausanne engagement is front-loaded. Everything decisive — the anticipating publication, the obviousness combination, the public-availability evidence — must be built for St. Gallen, because by the time an appeal reaches the Federal Supreme Court the factual door has largely closed.

EPFL, Health Valley and where the killer prior art hides

Lausanne is home to EPFL, one of Europe’s leading science and engineering universities and the engine of western Switzerland’s “Health Valley.” Around it sit the EPFL Innovation Park, Biopôle with its 200-plus biotech and medtech companies, and a dense cluster of robotics, neurotechnology and life-sciences spin-outs. That concentration produces two things at once: a steady flow of patents worth asserting, and the disputes that follow them.

The same academic engine is a prior-art goldmine. For an EPFL-adjacent claim, the reference that anticipates it is often not another patent but a thesis, a conference paper or a pre-print — frequently sitting in EPFL’s own Infoscience repository, published before the patent’s priority date. Robotics and medtech move fast and publish early, so the decisive disclosure regularly predates the filing by years.

• EPFL Infoscience — theses, dissertations and papers from the university’s labs
• Conference proceedings — IEEE robotics, medical-device and life-sciences venues
• Health Valley and Biopôle company disclosures, datasheets and product manuals
• Pre-prints, standards and archived project sites captured via the Wayback Machine

Because much of this literature lives outside the patent databases, dating it precisely to the priority date is the discipline that separates a real invalidity file from a search report — and it is exactly what technically trained Swiss judges will test.

How PerspireIP builds a patent invalidation Lausanne search

Every engagement starts the same way: 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. We then align the search to the forum you intend to use — the tight nine-month clock and grounds of an EPO opposition, or a nullity action or counterclaim before the Federal Patent Court in St. Gallen.

• Claim charting built for EPO opposition grounds and for Swiss nullity proceedings
• Deep non-patent-literature retrieval across EPFL Infoscience, IEEE and conference archives
• Public-availability dating for every reference, evidenced and defensible
• A record complete at first instance, because the Federal Supreme Court in Lausanne hears law, not new facts
• A written invalidity opinion and reference packages ready for the EPO or the court

We work alongside your Swiss and European patent attorneys and litigators as a specialist search partner, deliver to opposition and court deadlines, and keep every engagement confidential. Whether you are an EPFL medtech spin-out facing a device assertion, a robotics company defending a control-systems claim, or a life-sciences firm fighting a formulation patent, we scale to fit — a single search, a multi-patent campaign, or ongoing portfolio support. Send us the patent number and your key dates, and we will scope a patent invalidation Lausanne project within one business day.
