Frequently Asked Questions

Which court hears patent infringement cases for a Lyon company?

France centralises all patent litigation in one place: the Tribunal judiciaire de Paris has exclusive national jurisdiction over patent infringement and validity for the whole country, with specialised chambers and judges. A Lyon company, wherever it is based, litigates its French patent in Paris, with appeals to the Paris Court of Appeal and then the Cour de cassation. Unlike Germany, France does not bifurcate — the Paris court decides infringement and validity together. Paris also hosts a seat of the UPC Central Division for European patents.

What is a saisie-contrefaçon and why does it matter?

The saisie-contrefaçon, or infringement seizure, is France’s most distinctive evidence tool. On an ex parte order from the Paris court, a bailiff — often with a technical expert — can enter the alleged infringer’s premises before trial and inspect and seize samples, technical documents and manufacturing information. It is one of the most powerful evidence-gathering mechanisms in European patent litigation. But it is only as good as the technical analysis behind it: the request must say precisely what to look for and where the claimed features are likely to be, so the seizure captures evidence that actually maps to the claim.

How should a Lyon company choose between a French action and the UPC?

Since the Unified Patent Court opened, a European-patent holder can enforce nationally in the Tribunal judiciaire de Paris, covering France, or through the UPC, covering all participating member states in a single action — and Paris hosts a seat of the UPC Central Division. European patents can also be opted out of the UPC. A national action is confined to France but keeps a single familiar forum; the UPC offers pan-European relief but also pan-European revocation risk. The right route depends on the geographic footprint, the validity position and the patent’s opt-out status.

How is infringement proven for vaccine and chemical patents from Lyon?

Life-science and chemical claims hide their infringement questions in composition, sequence, formulation, process parameters and functional language rather than in a visible part. Proving infringement means characterising and testing the accused product or process and matching what is measured, feature by feature, to the claim, drawing on the scientific literature — exactly the kind of material a saisie-contrefaçon is designed to capture. We build the infringement read that the saisie is founded on and that the combined infringement-and-validity trial in Paris demands.

We map which patents and designations are in play and whether they sit inside or outside the UPC, then build the infringement and invalidity analysis to the forum chosen — keeping the technical story consistent if the dispute runs on both the French and the European tracks.

Claim charts and evidence of use for a Lyon assertion

The core deliverable is a claim chart that maps every feature of the asserted claim onto the accused product or process, in a form the Paris court can test and that a saisie can be built around. Because the French court decides infringement and validity together, a patent infringement analysis Lyon counsel can rely on has to build both reads on one claim construction from the outset.

  • Claim construction fixing the meaning of each disputed feature under French practice
  • Element-by-element charts mapping each feature to the accused product, process or composition
  • A targeting analysis for the saisie-contrefaçon, identifying what to seize and where
  • Evidence of use — characterisation, analytical testing and technical documentation, especially for life-science and chemical claims
  • A parallel invalidity and prior-art read, since validity is tried alongside infringement

For vaccine and chemical claims the evidence of use runs through characterisation and analytical testing; for cleantech and materials claims it runs through composition and performance data. In every case the chart is written so the Paris chamber can work through the claim feature by feature, and the invalidity search is built to the standard a combined infringement-and-validity trial demands.

How is infringement proven for vaccine and chemical patents from Lyon?

Life-science and chemical claims hide their infringement questions in composition, sequence, formulation, process parameters and functional language rather than in a visible part. Proving infringement means characterising and testing the accused product or process and matching what is measured, feature by feature, to the claim, drawing on the scientific literature — exactly the kind of material a saisie-contrefaçon is designed to capture. We build the infringement read that the saisie is founded on and that the combined infringement-and-validity trial in Paris demands.

These claims hide their infringement questions in composition, sequence, process parameters and functional language, so the evidence of use runs through characterisation, analytical testing and the scientific literature — exactly the kind of material a saisie is designed to capture. A credible infringement read has to be built by someone who understands the underlying science, not by a generic keyword pass over the patent.

National French action or the UPC? Coordinating the two

Since the Unified Patent Court opened, a Lyon company with a European patent has a choice of routes. It can enforce nationally in the Tribunal judiciaire de Paris, covering France, or through the UPC, covering all participating member states in a single action — and Paris hosts a seat of the UPC Central Division. European patents can also be opted out of the UPC to keep them in the national courts.

The routes differ in reach, procedure and risk. A national French action is confined to France but keeps the case in a familiar single forum; the UPC offers pan-European relief but also pan-European revocation risk if the patent falls. Which fits depends on the geographic footprint of the dispute, the strength of the validity position, and whether the patent has been opted out.

We build the infringement read that a saisie request is founded on, so the seizure is aimed precisely at where the infringement lives — and so the material it captures translates directly into a claim chart.

Vaccines, chemistry and cleantech: the Lyon docket

The Lyon region is concentrated in exactly the technologies that produce hard-fought patent disputes. Vaccines, diagnostics and biotechnology — anchored by the cluster around Marcy-l’Étoile and Lyonbiopôle — bring antibody, formulation, sequence and platform claims. The Vallée de la chimie brings chemical, catalyst, polymer and process claims. And a growing cleantech and hydrogen sector brings energy and materials claims.

  • Vaccine, biologic, diagnostic and formulation claims from the life-science cluster
  • Chemical, catalyst, polymer and process claims from the Vallée de la chimie
  • Cleantech, hydrogen, battery and energy-materials claims

The saisie-contrefaçon: France’s decisive evidence tool

The single most distinctive feature of French patent enforcement is the saisie-contrefaçon — an infringement seizure. On an ex parte order from the Paris court, a bailiff can enter the alleged infringer’s premises, inspect and seize samples, documents and technical information before any trial. It is one of the most powerful evidence-gathering mechanisms in European patent litigation, and it often determines the strength of the case that follows.

A saisie is only as good as the technical analysis behind it. The request has to identify, in advance, exactly what to look for and where the claimed features are likely to be found in the accused product or process, so the bailiff seizes evidence that actually maps to the claim. A vague saisie gathers little; a precisely targeted one, built on a real infringement read, can secure the decisive proof of use.

  • An ex parte seizure ordered by the Paris court before trial
  • A bailiff, often with a technical expert, inspecting and sampling the accused product or process
  • Seizure of technical documents, samples and manufacturing information
  • Evidence that must be tied, feature by feature, to the asserted claim

We build the infringement read that a saisie request is founded on, so the seizure is aimed precisely at where the infringement lives — and so the material it captures translates directly into a claim chart.

patent infringement analysis Lyon biotech vaccine and chemistry claim-chart study by PerspireIP for the Paris courts

A patent infringement analysis Lyon companies can rely on has to be built for a system that is centralised in a way few others are, because in France every patent dispute in the country is heard in a single court in Paris. Lyon is a powerhouse of vaccines, biotechnology, chemistry and cleantech — home to Lyonbiopôle, the vaccine and diagnostics cluster around Marcy-l’Étoile, and the Vallée de la chimie — but no patent case is tried locally.

The Paris Judicial Court (Tribunal judiciaire de Paris) has exclusive national jurisdiction over patents, and Paris is also a seat of the Unified Patent Court’s Central Division. A Lyon business enforcing or defending a patent therefore needs an analysis built for the French courts and for France’s distinctive evidence tools. PerspireIP builds the element-by-element claim charts, evidence-of-use packages and prior-art searches that the counsel who represent them depend on.

Where a patent infringement analysis Lyon case is heard

France concentrates all patent litigation in one place. The Tribunal judiciaire de Paris has exclusive jurisdiction over patent infringement and validity for the whole country, with a specialised set of chambers and judges, and appeals go to the Paris Court of Appeal and then the Cour de cassation. A Lyon company, wherever its business sits, will litigate its French patent in Paris.

Unlike Germany, France does not bifurcate: the Paris court decides infringement and validity together in the same proceeding. And since the arrival of the Unified Patent Court, Paris also hosts a seat of the UPC Central Division, giving European-patent holders a pan-European route alongside the national French one. National patents are granted by INPI, the French industrial-property office.

  • Tribunal judiciaire de Paris — exclusive national jurisdiction over French patent infringement and validity
  • Paris Court of Appeal and the Cour de cassation — the appellate route
  • UPC Central Division (Paris seat) — a pan-European route for European patents

It is one of the most powerful evidence-gathering mechanisms in European patent litigation, and it often determines the strength of the case that follows.

A saisie is only as good as the technical analysis behind it. The request has to identify, in advance, exactly what to look for and where the claimed features are likely to be found in the accused product or process, so the bailiff seizes evidence that actually maps to the claim. A vague saisie gathers little; a precisely targeted one, built on a real infringement read, can secure the decisive proof of use.

  • An ex parte seizure ordered by the Paris court before trial
  • A bailiff, often with a technical expert, inspecting and sampling the accused product or process
  • Seizure of technical documents, samples and manufacturing information
  • Evidence that must be tied, feature by feature, to the asserted claim

We build the infringement read that a saisie request is founded on, so the seizure is aimed precisely at where the infringement lives — and so the material it captures translates directly into a claim chart.

Vaccines, chemistry and cleantech: the Lyon docket

The Lyon region is concentrated in exactly the technologies that produce hard-fought patent disputes. Vaccines, diagnostics and biotechnology — anchored by the cluster around Marcy-l’Étoile and Lyonbiopôle — bring antibody, formulation, sequence and platform claims. The Vallée de la chimie brings chemical, catalyst, polymer and process claims. And a growing cleantech and hydrogen sector brings energy and materials claims.

  • Vaccine, biologic, diagnostic and formulation claims from the life-science cluster
  • Chemical, catalyst, polymer and process claims from the Vallée de la chimie
  • Cleantech, hydrogen, battery and energy-materials claims
  • Second-medical-use and dosage claims common in pharmaceutical disputes

These claims hide their infringement questions in composition, sequence, process parameters and functional language, so the evidence of use runs through characterisation, analytical testing and the scientific literature — exactly the kind of material a saisie is designed to capture. A credible infringement read has to be built by someone who understands the underlying science, not by a generic keyword pass over the patent.

National French action or the UPC? Coordinating the two

Since the Unified Patent Court opened, a Lyon company with a European patent has a choice of routes. It can enforce nationally in the Tribunal judiciaire de Paris, covering France, or through the UPC, covering all participating member states in a single action — and Paris hosts a seat of the UPC Central Division. European patents can also be opted out of the UPC to keep them in the national courts.

The routes differ in reach, procedure and risk. A national French action is confined to France but keeps the case in a familiar single forum; the UPC offers pan-European relief but also pan-European revocation risk if the patent falls. Which fits depends on the geographic footprint of the dispute, the strength of the validity position, and whether the patent has been opted out.

We map which patents and designations are in play and whether they sit inside or outside the UPC, then build the infringement and invalidity analysis to the forum chosen — keeping the technical story consistent if the dispute runs on both the French and the European tracks.

Claim charts and evidence of use for a Lyon assertion

The core deliverable is a claim chart that maps every feature of the asserted claim onto the accused product or process, in a form the Paris court can test and that a saisie can be built around. Because the French court decides infringement and validity together, a patent infringement analysis Lyon counsel can rely on has to build both reads on one claim construction from the outset.

  • Claim construction fixing the meaning of each disputed feature under French practice
  • Element-by-element charts mapping each feature to the accused product, process or composition
  • A targeting analysis for the saisie-contrefaçon, identifying what to seize and where
  • Evidence of use — characterisation, analytical testing and technical documentation, especially for life-science and chemical claims
  • A parallel invalidity and prior-art read, since validity is tried alongside infringement

For vaccine and chemical claims the evidence of use runs through characterisation and analytical testing; for cleantech and materials claims it runs through composition and performance data. In every case the chart is written so the Paris chamber can work through the claim feature by feature, and the invalidity search is built to the standard a combined infringement-and-validity trial demands.

Frequently Asked Questions

Which court hears patent infringement cases for a Lyon company?

France centralises all patent litigation in one place: the Tribunal judiciaire de Paris has exclusive national jurisdiction over patent infringement and validity for the whole country, with specialised chambers and judges. A Lyon company, wherever it is based, litigates its French patent in Paris, with appeals to the Paris Court of Appeal and then the Cour de cassation. Unlike Germany, France does not bifurcate — the Paris court decides infringement and validity together. Paris also hosts a seat of the UPC Central Division for European patents.

What is a saisie-contrefaçon and why does it matter?

The saisie-contrefaçon, or infringement seizure, is France’s most distinctive evidence tool. On an ex parte order from the Paris court, a bailiff — often with a technical expert — can enter the alleged infringer’s premises before trial and inspect and seize samples, technical documents and manufacturing information. It is one of the most powerful evidence-gathering mechanisms in European patent litigation. But it is only as good as the technical analysis behind it: the request must say precisely what to look for and where the claimed features are likely to be, so the seizure captures evidence that actually maps to the claim.

How should a Lyon company choose between a French action and the UPC?

Since the Unified Patent Court opened, a European-patent holder can enforce nationally in the Tribunal judiciaire de Paris, covering France, or through the UPC, covering all participating member states in a single action — and Paris hosts a seat of the UPC Central Division. European patents can also be opted out of the UPC. A national action is confined to France but keeps a single familiar forum; the UPC offers pan-European relief but also pan-European revocation risk. The right route depends on the geographic footprint, the validity position and the patent’s opt-out status.

How is infringement proven for vaccine and chemical patents from Lyon?

Life-science and chemical claims hide their infringement questions in composition, sequence, formulation, process parameters and functional language rather than in a visible part. Proving infringement means characterising and testing the accused product or process and matching what is measured, feature by feature, to the claim, drawing on the scientific literature — exactly the kind of material a saisie-contrefaçon is designed to capture. We build the infringement read that the saisie is founded on and that the combined infringement-and-validity trial in Paris demands.
