VLSI agrees to dismiss latest semiconductor patent complaint against Intel in Delaware

The Local Division Munich invalidated Promosome's licensed mRNA patent over Scripps' codon-optimisation method, then found BioNTech's Comirnaty vaccine would not have infringed the claims even had they been valid.

The Court of Appeal gave guidance on defending dependent claims, relying on EPO central limitation during UPC proceedings, and pleading revocation attacks. It also emphasised that inventive-step combinations require a proper pointer to the secondary reference.

In T 0903/24, the EPO Board of Appeal relied on reference numerals to interpret disputed claim language, rejecting the patentee's narrower reading and revoking novelty over prior art D2 for the main request.
