PCT System Updates: San Marino Joins DAS, Bahrain to Accept ePCT Electronic Filing, and Indonesia’s Biological Materials Collection Gains IDA Status

WIPO’s March 2026 PCT Newsletter highlighted a cluster of procedural developments that deserve close practical attention. Beyond the extension of certain PCT-PPH pilots, three updates stand out for their operational impact: the Patent and Trademark Office of San Marino will become both a depositing and an accessing Office of the WIPO Digital Access Service (DAS) from 1 May 2026; the National Patent Office of Bahrain will begin receiving and processing international applications in electronic form via ePCT-Filing from 1 October 2026; and the Indonesian Culture Collection (InaCC), under Indonesia’s National Research and Innovation Agency, has held the status of International Depositary Authority under the Budapest Treaty since 24 February 2026.

At first glance, these developments may look like separate technical notices. In reality, they point in the same strategic direction: the effectiveness of the PCT system increasingly depends not only on harmonized treaty rules, but also on the quality of its procedural infrastructure for priority document exchange, digital filing, and internationally recognized biological material deposits. For companies, research institutions and patent counsel, these changes may not alter patentability standards overnight, but they can materially affect filing readiness, evidence management and cross-border execution.

1. These are not isolated notices, but signs of continued infrastructure-level modernization in the PCT system

San Marino, Bahrain and Indonesia are each linked to a different procedural layer: priority documents, electronic filing and biological material deposits. The deeper point is that none of these changes rewrites the legal core of the PCT. Instead, they improve the practical interfaces through which applicants actually experience the system. That matters because the older view of the PCT as simply “one international application plus a timetable” is becoming too narrow. The ability to retrieve priority documents efficiently, to file through a standardized digital channel, or to align a biological-material-based invention with a recognized depositary framework is increasingly part of filing quality itself.

From a policy perspective, these updates show how WIPO continues to strengthen interoperability without imposing disruptive systemic reform. The benefit for applicants is reduced friction. Steps that once depended more heavily on paper documents, manual coordination or local procedural familiarity are gradually becoming more digital, more verifiable and more standardized. But the same trend also pushes risk upstream. Weak internal preparation will now show up earlier in the form of incomplete priority-document planning, immature e-filing workflows, or delayed biological deposit strategy.

2. Bahrain’s move to ePCT electronic filing matters most at the level of filing pathway and front-end compliance

The significance of Bahrain’s notification lies not merely in the fact that electronic filing becomes possible. More importantly, once Bahrain’s National Patent Office functions as a receiving Office using ePCT-Filing, applicants and agents gain access to a more structured international filing channel aligned with WIPO’s own digital environment. For businesses using Bahrain as part of a Gulf-based filing strategy, this may improve consistency in submission workflow, data validation, document packaging and access to the electronic filing fee reductions where applicable.

However, electronic filing should never be read as convenience alone. In practice, it often raises expectations for front-end information discipline. Once a filing team uses ePCT-Filing, applicant data, inventor details, priority claims, document versions, drawings, sequence listings and attachment formats all need tighter pre-submission control. Digital filing removes some physical friction, but not the need for substantive preparation. For law firms and patent agencies, this is a training and process issue. For in-house legal and R&D teams, it means there is less room for loosely coordinated last-minute completion.

3. San Marino’s DAS participation and InaCC’s new status reshape documentary proof and biotech preparation in different ways

San Marino’s accession to DAS as both a depositing and an accessing Office from 1 May 2026 may appear modest, but its value lies in making priority document retrieval and supply more predictable through a recognized digital channel. For applicants with an earlier filing connected to San Marino, or with a priority chain that may touch that Office, the change can reduce uncertainty around certified-copy handling and document transmission. In practical terms, better DAS connectivity is often less about symbolism than about lowering the chance of documentary friction at exactly the wrong procedural moment.

Indonesia’s InaCC development is different in legal form but equally important in practice. InaCC’s new role is under the Budapest Treaty rather than a direct amendment to the PCT itself. Even so, for inventions involving microorganisms or other biological material, this status change feeds directly into PCT filing strategy because internationally recognized deposit arrangements can be closely tied to sufficiency, deposit certification and later national phase stability. The recognition of InaCC may therefore improve geographic convenience and coordination options for applicants in Southeast Asia, especially research institutions, biotech companies and cross-border R&D collaborations that need a credible regional deposit pathway.

4. Practical takeaway for applicants and counsel: procedural convenience only creates value when turned into earlier internal control

The first lesson is that these updates should not be treated as background news items. They are better understood as triggers for internal process adjustment. Teams that may file via Bahrain should review whether they are ready for ePCT permissions, workflow design and document-format discipline. Teams handling priority chains linked to San Marino should revisit their knowledge of DAS timing and eligibility. Teams working on biological-material inventions should move depositary selection and supporting evidence preparation earlier in the drafting and filing cycle.

The second lesson is more strategic. Competitive advantage in the PCT system increasingly comes from how smoothly an applicant can connect to the system’s procedural infrastructure. For larger companies, that means integrating priority management, digital filing and special-subject-matter compliance into a more coherent global filing framework. For smaller innovators, it means relying less on ad hoc fixes and more on disciplined preparation. These are not headline-grabbing reforms, but that is precisely why they matter: infrastructure updates often change day-to-day filing quality and international coordination sooner than major legislative amendments do. The real advantage lies not in knowing that the notices exist, but in converting them into fewer errors, stronger evidence chains and more reliable cross-border filing execution.
