Detailed Summary

Düsseldorf Local Division

UPC_CFI_505/2024

of the Court of First Instance of the Unified Patent Court

delivered on 13 May 2025

concerning EP 3 536 712 B1

Headnotes:

1.

In the case of a second medical use claim, a substance or composition within the mean-

ing of Art. 54(4) EPC is used for any specific use which is not comprised in the state of

the art. Such a therapeutic use can be a new indication, e.g. a disease not yet treated

by the claimed substance, or an indication for a new group of patients.

2.

For a finding of infringement of a second medical use claim, the alleged infringer must

offer or place the medical product on the market in such way that it leads or may lead

to the claimed therapeutic use of which the alleged infringer knows or reasonably

should have known that it does. The requirements of such behaviour cannot be defined

in an abstract manner but require an analysis of all relevant facts and circumstances of

the patent claim in question.

3.

In order to benefit from the notional novelty afforded by Art. 54(5) EPC, second medical

use claims must relate to a specific use in a method according to Art. 53(c) EPC. The

sole reason why such claims can still be patented is the novelty (and inventiveness) of

the new use.

4.

In terms of inventive step, the subject matter of the claim may be obvious if the skilled

person would have been motivated to implement it as the next step in the view of the

problem. A motivation to implement may be absent or negated if the skilled person is

faced with many uncertainties or expected difficulties. If there is no motivation at all

or a negated motivation, the subject matter of the claim is not obvious and involves an

inventive step.

5.

Objections based on pleading ignorance are in principle disregarded. The Rules of Pro-

cedure of the Unified Patent Court do not acknowledge this type of pleading.

Second medical use claim; infringement; novelty; pleading ignorance; inventive step; obviousness

This order concerns a patent infringement action relating to European Patent No. EP 2 746 957, in which the claimant Total Semiconductor, LLC sought review of an order by the judge-rapporteur requiring it to provide security for costs under Rule 158 RoP. The defendants (Texas Instruments entities) had requested security for costs, arguing that the claimant, a recently founded US-based licensing entity operating from a co-working space and funded by third-party investors, posed an enforcement and insolvency risk. The claimant opposed, contending that the defendants failed to establish sufficient facts demonstrating a real risk that cost reimbursement could not be satisfied or enforced.
