Prior Art Litigation Search in Lausanne.

A prior art search Lausanne accused infringers can rely on has to fit the Swiss system exactly, not a borrowed European template. Switzerland sits at the heart of Europe but is neither in the EU nor part of the Unified Patent Court, so a patent asserted against a Lausanne company is fought under Swiss law before one specialised national court. That court — the Swiss Federal Patent Court in St. Gallen — hears infringement and validity together, and its rulings are appealed to the Swiss Federal Supreme Court here in Lausanne. PerspireIP builds nullity- and opposition-grade invalidity searches for the medtech, life-science, robotics and hardware companies defending patents across the Lake Geneva region.

Where a prior art search Lausanne case is heard

Swiss patent disputes are not tried in the local cantonal courts of Vaud. Since 2012 a single specialised court — the Swiss Federal Patent Court (Bundespatentgericht / Tribunal fédéral des brevets) in St. Gallen — has held exclusive nationwide jurisdiction over both patent infringement and patent validity. That unified design is Switzerland’s defining advantage: unlike the German bifurcated system, one court, staffed by technically-qualified judges, decides whether a patent is infringed and whether it is valid in the same proceeding.

For a Lausanne defendant that matters, because invalidity is raised as a counterclaim or defence in the same case, on the same record. Appeals from the Federal Patent Court go to the Swiss Federal Supreme Court (Bundesgericht / Tribunal fédéral), which sits in Lausanne itself — so the final word on Swiss patent validity is handed down in the city. A prior art search Lausanne plan has to be built for that forum from day one.

The Federal Patent Court’s panels combine legally-qualified and technically-qualified judges, so an invalidity argument is read by people who understand the science, not only the law. Proceedings can be run in any Swiss official language, and the court accepts English-language documents and evidence, which matters for the multinational medtech and hardware companies clustered around Lausanne. For a defendant in French-speaking Vaud, that means a genomics paper, an engineering standard or a foreign patent can be put straight into the record and argued on its technical merits.

• Swiss Federal Patent Court (St. Gallen) — exclusive first-instance court for infringement and validity, with technical judges
• Nullity action / invalidity counterclaim — how a Swiss patent is challenged, decided on prior art
• Swiss Federal Supreme Court (Lausanne) — the appeal court for Federal Patent Court judgments
• EPO opposition — the central attack on a European patent validated in Switzerland, within nine months of grant

Switzerland is outside the UPC — why that changes the search

Switzerland is not in the European Union and is not a member of the Unified Patent Court. The UPC and the unitary patent do not extend to Swiss territory, so a European patent takes effect in Switzerland only as a national Swiss part, validated through the Swiss Federal Institute of Intellectual Property (IPI) and entered on the Swissreg register. Enforcement and revocation of that Swiss part happen before the Swiss Federal Patent Court under Swiss law — not in Paris, Munich or Milan.

This has a direct effect on strategy. A defendant cannot rely on a UPC central revocation to clear the Swiss market, and a competitor’s UPC opt-out decisions are irrelevant to the Swiss part. The two live routes to destroy the patent are a Swiss nullity action before the Federal Patent Court and, for a European patent still inside its opposition window, an opposition at the EPO. Both stand or fall on prior art, and both are firmly in scope for a defendant in the Lake Geneva economy.

There is a further wrinkle unique to Switzerland. Purely national Swiss patents granted by the IPI are not examined for novelty or inventive step before grant — only formalities and patentable-subject-matter are checked. Validity is therefore tested for the first time when the patent is challenged, which puts the whole weight of the case on the prior-art record a defendant assembles. Where the asserted right is a national Swiss patent rather than a validated European one, a rigorous invalidity search is not just useful; it is the entire fight.

EPFL and Health Valley: where Lausanne’s prior art lives

Lausanne’s innovation base is exceptional for a city its size. EPFL has spun out hundreds of deep-tech companies, and the wider canton of Vaud anchors Switzerland’s Health Valley — a dense life-science cluster spanning the Biopôle campus in Epalinges, EPFL Innovation Park, and hundreds of medtech, biotech and diagnostics firms. Sophia Genetics, MindMaze and a long tail of EPFL medtech and surgical-robotics spin-outs make life-science and device patents the marquee local litigation theme.

Medtech and life-science claims are heavy obviousness and enablement terrain, and their anticipating art is overwhelmingly non-patent literature. For a diagnostic, device or biotech claim, the reference that reads on the claim is far more often a journal paper, a clinical abstract or a conference proceeding than another patent.

The corporate depth around the lake reinforces the theme. Nestlé runs major research nearby in Vevey, Debiopharm and a long roster of biotech and diagnostics firms operate across Vaud, and the whole ecosystem generates a steady stream of device, formulation and diagnostic patents that end up asserted or defended. When a Health Valley company is accused of infringement, the invalidating disclosure has frequently already been published in that same scientific community — in a paper, a poster or a trial write-up that predates the patent. Finding and dating it is the core of the defence.

• PubMed / MEDLINE, clinical-trial registries and peer-reviewed journal archives
• Conference proceedings and abstract books for medtech, genomics and neurotech
• EPFL and university theses, preprints and datable technical disclosures
• Earlier European, Swiss, US and PCT patent families argued as inventive-step combinations

Robotics, drones and hardware: dating the earlier disclosure

Beyond life science, the region runs on robotics, drones, precision hardware and consumer electronics. EPFL’s robotics labs have produced companies working on inspection drones and surgical robotics, Logitech is headquartered in the canton of Vaud, and Nestlé runs major research nearby in Vevey. That mix makes robotics, sensor, imaging and mechanical patents a recurring source of Swiss disputes — and the invalidating art for them is frequently a demo, a datasheet or a research video rather than a granted patent.

Because so much of that art is a dated public disclosure rather than a formal publication, we treat public-availability dating as evidence to be proved — establishing that each reference, product release or video was genuinely accessible before the patent’s priority date, to the standard the Federal Patent Court and an EPO opposition division expect.

Lausanne is also the Olympic Capital, home to the International Olympic Committee and many international sports federations, which has grown a distinctive sports-tech and wearables scene alongside the consumer-hardware heritage of Logitech. Patents on sensors, timing systems, wearables and human-motion capture surface here, and their prior art often sits in older product releases, athletics-technology papers and demonstration footage rather than in a patent database. That is exactly the kind of scattered, date-sensitive art an invalidity search has to run down and pin to a verifiable public date.

• IEEE Xplore, ICRA/IROS robotics proceedings and standards documents
• Product manuals, datasheets and archived spec pages with datable histories
• Trade-show disclosures, dated press coverage and demonstration videos
• Earlier patent families across the EPC, US and PCT routes for obviousness attacks

Swiss nullity action or EPO opposition? Choosing the route

A Lausanne defendant facing a European patent validated in Switzerland often has more than one way to attack it, and they are not interchangeable. An opposition at the EPO is central: it can revoke the patent for every EPC state at once, including the Swiss part, but it must be filed within nine months of the mention of grant. Its grounds are essentially novelty, inventive step, added matter and insufficiency, all decided on prior art.

A Swiss nullity action or invalidity counterclaim before the Federal Patent Court is available at any time and is the only route once the opposition window has closed — or where you need validity resolved together with an infringement case for the Swiss market specifically. It can also proceed while an EPO opposition runs, and the court may stay proceedings to await the EPO outcome. The two tracks call for the same foundation: a rigorous, well-dated prior-art record.

Timing and forum drive the choice, but the search does not change: one thorough invalidity search can feed an EPO opposition brief and a Federal Patent Court nullity case at the same time. Getting that search right early is what keeps both options open.

No local patent counter — and why it doesn’t matter

The Swiss Federal Institute of Intellectual Property sits in Bern, the Federal Patent Court sits in St. Gallen, and the EPO examines and hears oppositions in Munich, The Hague and Berlin. There is no patent tribunal counter in Lausanne itself — only the Federal Supreme Court, the appeal instance. None of that geography changes a validity fight.

What decides the case is not proximity to an office but the strength and dating of the prior art. A Swiss nullity action is briefed on documents and argued before technical judges; an EPO opposition is largely written, with oral proceedings that can be attended remotely. Whether the killer reference is a genomics paper for a diagnostic claim or a robotics demo for a drone patent, the work is the same — finding it, and proving it was public before the priority date.

How PerspireIP builds a prior art search Lausanne

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 medtech, life-science, robotics and hardware subject-matter we run patent and deep non-patent-literature searching in parallel, then build claim charts that a Federal Patent Court technical judge or an EPO opposition division can follow line by line.

• Claim charting mapped to novelty and inventive step under the EPC and Swiss Patents Act
• Deep retrieval across PubMed, IEEE, ICRA/IROS, clinical registries, patents and product records
• Public-availability dating for every reference, evidenced to Swiss and EPO standards
• Prior art sized to your route — the EPO’s nine-month opposition window or a Federal Patent Court nullity action
• A written invalidity opinion and reference packages ready for the court or the opposition division

We work alongside your Swiss patent attorneys and litigation counsel as a specialist search partner, deliver to court and EPO deadlines, and keep every engagement confidential. Whether you are an EPFL spin-out defending a device patent, a Health Valley diagnostics company facing an assertion, or a hardware maker fighting a robotics claim, we scale to fit — a single search, a multi-patent campaign or ongoing support. Send us the patent number and your key dates, and we will scope a prior art search Lausanne project within one business day.
