Intellectual Property in Switzerland: Patents, Trademarks, and the Patent Box

Switzerland has a sophisticated intellectual property framework administered by the Institut fur Geistiges Eigentum (IGE — IPI in French and English, at ige.ch). The country is a signatory to all major international IP conventions — the European Patent Convention (EPC), the Patent Cooperation Treaty (PCT), the Madrid System for trademarks, and the Berne Convention for copyright — making it a straightforward jurisdiction for both national and international IP protection. For companies, the interaction between IP ownership and the cantonal patent box regime is one of the most powerful tax planning tools Switzerland offers.

IP rights at a glance

Patents

Swiss patents are governed by the Patentgesetz (PatG). A patent grants the holder a 20-year exclusive right to the invention, calculated from the filing date. Switzerland applies full substantive examination — novelty, inventive step, and industrial application must all be demonstrated. The IGE's patent examination is thorough; it typically takes three to five years from filing to grant for complex technical inventions.

Filing routes

• �National (IGE): Protection in Switzerland and — under the bilateral CH-LI treaty — Liechtenstein. Appropriate for inventions primarily commercialised in Switzerland.
• �European Patent (EP via EPO): Switzerland is an EPC contracting state. A European patent designating Switzerland, once granted by the European Patent Office, has the same effect as an IGE national patent. The EP route is efficient for companies needing protection across multiple European markets.
• �PCT (WIPO): The Patent Cooperation Treaty allows a single international filing with simultaneous effect in 150+ countries. The PCT application enters the national phase (at each country's national office, including IGE) after 30 months from the priority date. Preferred for companies with global commercialisation plans.

Trademarks

Trademark protection in Switzerland is governed by the MSchG. A mark must be distinctive, not descriptive of the goods or services, and not contrary to public policy. Registration is for 10 years and is indefinitely renewable. Swiss trademark registration at the IGE protects the mark in Switzerland and, under the bilateral arrangement, in Liechtenstein.

For international protection, Swiss companies most commonly use the Madrid System administered by WIPO: a single application in one language designates protection in up to 130 countries, using the Swiss IGE registration as the base mark. The EUIPO (European Union Intellectual Property Office) is a separate route for EU trademark protection and does not cover Switzerland (which is not an EU member).

Designs and copyright

Industrial designs

The Designgesetz (DesG) protects the appearance of a product — its shape, lines, colours, and texture. Registration is for an initial five years, renewable up to a maximum of 25 years. Switzerland is a member of the Hague System (WIPO), allowing international design protection through a single filing. For consumer goods, fashion, and precision instruments, design registration is an important complement to patent and trademark protection.

Copyright

Copyright under the Urheberrechtsgesetz (URG) arises automatically upon creation of a qualifying work — literary, artistic, musical, audiovisual, or software. No registration is required or possible in Switzerland. Protection lasts for 70 years after the death of the author (for most works). For companies, copyright in software and technical documentation is a significant asset, but it cannot be used as a qualifying right for the patent box (see below).

The patent box: cantonal tax relief on IP income

The patent box is the most commercially significant IP-related tax measure available to Swiss companies. Introduced as part of the TRAF (Tax Reform and AHV Financing) reform and implemented in cantonal law under StHG Art. 24a, the patent box provides a cantonal income tax reduction on net income derived from qualifying IP.

How the patent box works

• �Qualifying rights: Patents registered in Switzerland or equivalent jurisdictions, and analogous rights (supplementary protection certificates, utility models where recognised). Software copyright does NOT qualify; pure trademarks do NOT qualify.
• �Qualifying income: License income, royalties, and a notional royalty carved out of product sales revenue attributable to qualifying IP (using a nexus-based formula). Income must be linked to a specific qualifying right.
• �Maximum relief: Up to 90% reduction of the cantonal income tax base attributable to qualifying IP income.
• �Zug implementation: Zug has implemented the patent box at the maximum 90% relief level. Combined with the standard Zug corporate income tax rate, the effective cantonal and communal CIT rate on qualifying IP income in Zug can be approximately 1.185% — among the lowest effective rates in Europe for patent income.

Domain names and trade secrets

Domain names (.ch)

There is no separate Swiss law governing domain names. The .ch country-code top-level domain is administered by SWITCH (switch.ch) on a first-come, first-served basis. Domain disputes are resolved through WIPO arbitration under the Rules for Uniform Domain Name Dispute Resolution applicable to .ch domains. Trademark holders can challenge registrations made in bad faith (cybersquatting), but must demonstrate the domain was registered in bad faith and corresponds to their trademark.

Trade secrets

Switzerland protects trade secrets through the Unfair Competition Act (UWG) and general OR principles. There is no formal registration mechanism. Protection depends on the company maintaining genuine secrecy: limiting access, implementing confidentiality agreements with employees and suppliers, and maintaining internal security protocols. A trade secret that is not actively protected can lose legal protection. Trade secret misappropriation is actionable both civilly (UWG Art. 5, OR Art. 41) and criminally (Criminal Code Art. 162).
