Bagless vacuum cleaner patent litigation in France:

Evidence obtained through improperly conducted saisie-contrefaçon is vacuum cleaned by the Court of Paris

In the high profile patent case of Dyson v. Hoover, the judgment handed down by the English Court of Appeal on 4 October 2001 resulted in a full victory for the claimant. European Patent 0 042 723 for a bagless vacuum cleaner was held valid and infringed as it was found in the Patents Court.

The outcome of a similar case launched by Dyson in France was completely differ­ent, for purely procedural reasons. On the 11th December 2001, the Tribu­nal de Grande Instance (Court of First Instance) in Paris dismissed the complaint of Dyson against the Korean manufacturer LG Electronics, based also on EP 0 042 723. The Court did not deal with validity nor with infringe­ment. The case was dismissed just because the saisie-contrefaçon (search and seizure) was not properly conducted.

Saisie – as it is widely known – is a powerful way to obtain evidence of infringement: when shown a copy of the patent in force the Court must permit ex parte the patent holder to have an huissier (a bailiff, a public officer) conduct search and seizure in the premises of the alleged infringer. Article L.615-5 of the French Intellec­tual Property Code reads as follows:

“The owner of a patent application or the owner of a utility certificate application or the owner of a patent or of a utility certificate shall have the possibility of furnishing proof by any means whatsoever of the infringement of which he claims to be a victim. 

He shall further be entitled, on an order given by the President of the First Instance Court of the place of the presumed infringement, to direct any bailiffs, accompanied by experts of his own choice, to proceed with a detailed description, with or without effective seizure, of the allegedly infringing articles or processes. Such order shall be provisionally enforced. It may be subjected to a security on the part of the plaintiff. In that same order, the President of the Court may authorize the bailiff to carry out any enquiry required to ascertain the origin, nature and scope of the infringement. 

The same right shall be enjoyed by the licensee of an exclusive right of working under the conditions laid down in the second paragraph of Arti­cle L. 615–2 and in the fourth paragraph of Article L. 615–2, by the holder of a license of right, a compul­sory license or an ex–officio license in accordance with Articles L. 613–10, L. 613–11, L. 613–15, L. 613–17 and L. 613–19.

If the petitioner fails to institute proceedings before a Court within a term of 15 days, the seizure shall automatically be void, without preju­dice to any damages.”

Therefore, the bailiff who performs seizure may have the assistance of experts chosen by the plaintiff who are usually the plaintiff’s patent attorneys. In some cases, the plaintiff appoints other people such as university profes­sors to assist the bailiff.

According to a leading judgment1 of the Cour de Cassation, the French Supreme Court for civil cases, the expert who assists the bailiff for a saisie cannot be chosen among the plaintiff’s employees. The rationale was in article 6-1° of European Convention on Human Rights: the Court held that the right to a fair trial means that the expert must be independent from the parties.

In the Dyson v. LG Electronics case, the bailiff was assisted by two Dyson employees (a technician who disassem­bled the vacuum cleaning unit to allow the description of its inner mechanism and the advertising manager who helped the bailiff in his description). The Court of Paris found that such assistance was not permitted and there­fore held the saisie invalid. As the plaintiff did not submit any other evi­dence of the alleged infringement, the case was dismissed. This judgment shows that the saisie is a powerful tool but that it must be used with care. Otherwise the evi­dence gathered will be… vacuum cleaned.
