Pursuant to Section 124A of the Patents Act 1977, the UK Intellectual Property Office (IPO) has enacted a mandatory transition from legacy infrastructure to the unified "One IPO" digital platform. This operational overhaul fundamentally restructures the submission, prosecution, and maintenance of UK patents, with subsequent phases slated to absorb Trade Marks and Registered Designs.

1. System Infrastructure and Account Architecture

Disparate communication channels including legacy electronic filing tools, the European Patent Office Online Filing (eOLF) software, and designated email submittal mailboxes (e.g., forms@ipo.gov.uk) are systematically decommissioned. Applicants and legal representatives must manage portfolios via a centralised digital user account. This interface enables real-time tracking, multi-user collaborative drafting without linear input constraints, and instant self-service execution of renewals and changes to designated representation.

2. Technical Submission Specifications

To facilitate automated machine-readability, unified patent specifications are prohibited. Documentation must be unbundled and submitted across independent, prescribed formats:

• Descriptions & Claims: Must be submitted exclusively in .docx or .odt formats. Font size must be a minimum of 10. Documents must be devoid of metadata, active tracked changes, embedded user comments, alternative text, or Object Linking and Embedding (OLE) objects.

• Drawings: Restricted to .pdf format.

• Abstracts: Must be input as unformatted text directly into the web interface.

• Sequence Listings: Must comply with WIPO Standard ST.26 and be submitted in .xml format.
  

3. Transitional Provisions and Statutory Safeguards

To mitigate initial technical disruptions, a temporary filing mechanism is established:

1. Protective Filing: Applicants may upload a unified specification as a traditional .pdf under "supporting documents" while uploading blank .docx/.odt files to bypass system constraints and secure an immediate provisional filing date.
   

2. Rectification Window: The applicant has a strict two-month statutory window from the initial filing date to submit the formal, separated, machine-readable .docx or .odt files. These must match the original text exactly.
   

3. Sanctions: Failure to provide compliant files within this two-month period results in the application being automatically treated as withdrawn by operation of law.
   

4. Security Screening and Receipts

The issuance of filing receipts is bifurcated. Automated system confirmations are generated immediately upon submittal. However, the legally binding formal filing receipt is withheld until the application successfully clears mandatory national security vetting under Section 22 of the Patents Act 1977. International filings designating the UK via the Patent Cooperation Treaty (PCT) must now route exclusively through WIPO’s ePCT service.
