The Swiss patent system is undergoing its most comprehensive modernisation in decades following the Federal Council’s formal approval of the completely revised Patents Ordinance.
Designed to increase legal certainty, streamline administrative procedures, and align Swiss practices with international standards, the new legislative framework is officially scheduled to take effect on 1 January 2027.
The overhaul follows a partial revision of the Patent Act passed by the Federal Assembly in March 2024, which subsequently received broad approval during a public consultation phase in mid-2025. The updated framework introduces major structural adjustments to application processing, transparency, fee structures, and dispute resolution.
Introduction of Full Substantive Examination
Under the current system, the Swiss Federal Institute of Intellectual Property (IPI) reviews applications primarily for formal compliance and excluded subject matter, bypassing an in-depth evaluation of novelty and inventive step.
From 2027, a dual-track system will be introduced. While applicants can still choose to maintain a partially examined patent, they will now have the option to request a full substantive examination that evaluates the invention against global standards of novelty and inventive ingenuity. This structure aims to provide businesses with the flexibility to secure a more robust, legally resilient national patent.
Mandatory Prior-Art Searches
To improve transparency and patent quality, a prior-art search will become mandatory for all future Swiss patent applications. Mirroring international standards, the IPI will generate a search report detailing relevant state-of-the-art documentation. This report will be attached to every patent, allowing applicants and third parties to better assess whether an invention is eligible for protection. Currently, such searches are entirely voluntary and must be requested separately.
Streamlined Appeals and Structural Changes
The reform alters how patent disputes are handled in Switzerland. The existing opposition procedure at the IPI, which has historically seen no usage, will be dismantled. Instead, under the new framework, decisions made by the IPI can be appealed directly by applicants or third parties to the Federal Patent Court, which replaces the Federal Administrative Court as the competent appellate body.
Notably, despite prior legislative discussions, Switzerland decided against introducing a separate utility model system as part of this reform package. The Federal Council is simultaneously amending portions of the trade mark and design ordinances to ensure that administrative and appeal procedures across all industrial property rights are harmonised.
Language Modifications and New Fee Structure
In an effort to attract international applicants and reduce administrative barriers, the IPI will begin accepting technical documentation written in English.
The enhanced examination procedures and mandatory elements have resulted in a reconfigured fee structure:
- Filing & Claims: The standard application fee remains 200 Swiss francs, but it will now cover up to 15 claims, an increase from the previous limit of 10.
- Mandatory Search: A new mandatory prior-art search fee of 500 Swiss francs will apply to all applications.
- Examination Tracks: A partial substantive examination will cost 400 Swiss francs (a reduction from the previous 500 Swiss francs), while opting for a full substantive examination will require an additional fee of 300 Swiss francs.
- Renewals: To offset implementation costs, overall patent renewal fees will increase by approximately 8% over the maximum 20-year term. In line with European standards, these maintenance fees will now become payable starting from the third year after filing, rather than the fourth.
Transitional Provisions for Pending Applications
When the law takes effect on 1 January 2027, pending applications for which the examination fee remains unpaid will automatically transition to the new legal framework and undergo the updated review process.
Conversely, applications at a highly advanced stage where the examination fee was paid prior to 1 January 2027 and no deferral is in place will be completed under the legacy rules without automated novelty or inventive step scrutiny. However, applicants holding these advanced pending files can explicitly request to opt into the new examination framework if they wish to secure a fully examined patent.
Because the statutory deadline to challenge the legislation via the Swiss optional referendum process passed without a challenge, the reform is legally finalised and fully cleared for its 2027 rollout.
Navigating the 2027 Swiss Patent Transition
The fast-approaching 1 January 2027 implementation deadline creates immediate risks and strategic opportunities for existing patent portfolios. Deciding whether to accelerate pending files under legacy rules or embrace the robust new dual-track framework requires careful analysis of your market objectives and competitors.
