New biological sequence listings requirements for patent applications

From 1 July 2022 a new global standard will apply to all new patent applications containing biological sequence listings.

This change is being adopted by all WIPO contracting states including the UKIPO. Details of WIPO ST.26 are available.

New software, WIPO Sequence, is available for applicants to compile sequence listings.

10-day rule

At a meeting held by the EPO Committee on patent law on Thursday 12 May 2022, a proposal for ‘dropping’ the 10-day notification rule was preliminarily approved.  The proposal still needs to be approved at the Administrative Council meeting at the end of June, but if it passes there too we could expect this change to come into force on 1 February 2023.  The proposed change would abolish the 10-day rule regardless of whether communications are delivered electronically or by post.  We will keep a close watch on this so that we can keep our clients informed.

Suspension of the PPH programmes between the EPO and Russia

MyEPO Portfolio

The EPO is launching MyEPO Portfolio, a secure, web-based online service for parties to proceedings before the EPO. It is designed to improve accessibility, enable the exchange of digital information and provide improved procedural guidance.  After its launch, MyEPO Portfolio will be accessible from MyEPO, an area on the EPO website that will provide access to a variety of EPO online services in the future, with additional services added over time. A suite of user guides and tutorials will be available for each service.


Candidates have been reminded that, with effect from 1 January 2021, all correspondence from the Examination Secretariat is conducted in electronic form only, via the myEQE portal.  This goes for all appealable decisions too.  The requirement to use registered mail is removed.

Submissions made by other parties in appeal proceedings

As of 1 June 2022, in all inter partes appeal proceedings, the Boards of Appeal has adapted their practice of informing the parties of submissions and documents which are filed by a party to the proceedings or by a third party.  Party submissions, in particular the notice of appeal, the statement of grounds of appeal and the reply to the statement of grounds, will continue to be communicated to the other parties.  However, copies of all documents attached to party submissions, including patent and non-patent literature cited in party submissions as well as documents containing amendments, such as an amended set of claims, are no longer to be forwarded automatically.  All these documents contained in the electronic file can be downloaded from the European Patent Register.  They will be provided to the parties free of charge in paper form upon request only.  The Boards of Appeal’s practice of informing the other parties of the filing of items or documents which are not available for inspection in the electronic files of the European Patent Register (e.g. non-scannable objects, non-public documents) or are not easily legible (e.g. documents filed in colour) is retained.

From 1 April 2022, the EPO as receiving office will no longer systematically attach a copy of the received request form (PCT/RO/101) to the Form PCT/RO/105 (notification of the international application number and filing date). This will only be sent in cases of ex officio correction(s) by the receiving office.  This is intended to allow applicants to immediately identify whether the receiving office made a change to the request form.  More here (page 7).
