Introduction

In decision T 0483/22 dated May 3, 2024, the European Patent Office's Technical Board of Appeal examined critical issues regarding the validity of priority claims and the novelty of a modular cabin segment patent. The case involved a patent owned by Airbus Operations GmbH, which was challenged by Diehl Aviation Hamburg GmbH. The decision is particularly noteworthy for its analysis of whether the claimed invention was novel and whether it validly claimed priority. The Board ultimately upheld the revocation of the patent, providing important insights into the application of Articles 54 and 87 of the European Patent Convention (EPC).

Summary of the Invention

The patent in question, EP 2 675 710, relates to a modular cabin segment designed for vehicles, particularly aircraft. The invention describes a configuration of various modules, including toilet and galley modules, which can be arranged to optimize space within the cabin. A key feature is the integration of a partition wall between toilet compartments, which can be moved to combine the compartments into a larger space. The modular nature of the segments allows for flexibility in cabin design, catering to different operational needs.

Key Points of the Decision

1. Priority Claim Validity (Article 87 EPC)

The Board focused on whether the priority claimed by the patent was valid, particularly in relation to the disclosure in the priority documents P1 and P2. The opponent argued, and the Board agreed, that the priority claim was not valid because the subject matter of the patent could not be directly and unambiguously derived from the priority documents. The Board highlighted that essential features, such as the cabin attendant seat, were integral to the invention as disclosed in the priority documents, and their omission in the patent application led to the invalidation of the priority claim.

2. Novelty (Article 54 EPC)

Given that the priority claim was deemed invalid, document D1 became relevant prior art. The Board assessed whether the modular cabin segment described in the patent was novel over D1. The opponent successfully argued that D1 disclosed a similar modular configuration, including functional modules that could be linked in the manner claimed by the patent. The Board concluded that the subject matter of the patent lacked novelty in light of D1, leading to the decision to revoke the patent.

3. Auxiliary Requests and Admittance (RPBA 2020)

The patent proprietor submitted multiple auxiliary requests in an attempt to amend the claims and overcome the objections. However, the Board did not admit these requests into the proceedings, citing that they should have been filed earlier during the opposition proceedings. The Board emphasized the principles of procedural economy and the need for timely submission of amendments.

Lessons to Be Learned

1. Ensuring Consistency Between Priority Documents and Patent Claims

This decision reinforces the importance of ensuring that all critical features disclosed in the priority documents are included in the patent claims. Omitting key features can lead to the invalidation of priority claims, which can then expose the patent to prior art that might invalidate its novelty.

2. Importance of Novelty in Patent Claims

The case underscores the necessity of thoroughly assessing the novelty of patent claims, especially in relation to prior art. The broad interpretation of "modular cabin segment" by the Board demonstrates that patentees must be vigilant in distinguishing their inventions from existing technologies.

3. Strategic Use of Auxiliary Requests

The decision highlights the risks associated with late filing of auxiliary requests. Patent proprietors should ensure that any necessary amendments are made during the opposition stage to avoid rejection of those requests in appeal proceedings.
