When Is It Time to Patent an Invention?
Whenever you create something new, the first step is to document it in a short invention disclosure. From there, you face a strategic choice that will shape your ability to use, protect, and monetize your idea.
- Publish your invention: Publishing establishes you as the inventor and creates prior art, preventing others from patenting the same idea. This approach can secure your freedom to operate, but it does not grant exclusive rights—others remain free to use the invention.
- File a patent A patent gives you exclusive rights to your invention for many years in the countries where protection is granted. It allows you to control and potentially block others from using your technology without permission. However, patents come with important trade-offs:
- You must fully disclose your invention, enabling others to use it once the patent expires
- The process is costly, especially for international protection
- Enforcement is your responsibility—you must be prepared, both strategically and financially, to defend your rights globally
- Keep it as a trade secret: Maintaining Maintaining your invention as a trade secret avoids disclosure and can provide long-term protection—as long as confidentiality is preserved. This strategy works best for technologies that are difficult to reverse-engineer and can be tightly controlled.
How to Proceed with a Patent Application
When Time Is Critical
If speed is essential, it is often best not to delay with extensive prior art research. Instead, you can file a provisional patent application within a few days (see below: How to Apply for a Patent in Urgent Cases). This allows you to quickly secure an early filing date while refining your invention later.
When Time Allows
If timing is less critical, a more thorough approach is recommended. Conducting a prior art search helps you assess novelty and refine your claims. Based on these insights, you can prepare a well-structured patent application with stronger protection potential. At the Swiss Federal Institute of Intellectual Property, individuals with permanent residence in Switzerland may file a patent application independently. For applications at the European Patent Office, applicants must have a residence or principal place of business in Europe. If this is not the case, the application must be submitted through a qualified European Patent Attorney.
Expert Guidance
Patent applications are highly technical and strategic documents. If you have any uncertainty, it is strongly recommended to consult a patent specialist—both for drafting the application and for selecting the most appropriate filing strategy.
Prior Art Search You can do a prior art search in the following patent data bases (no fees and open access) - in case of uncertainty please contact a search specialist.
*Also a low cost alternative is to file a German patent application in German (official fees at the German Patent Office Euro 400++) which delivers a detailed search report after 18 months with respect to prior art. But if you have no residence in Europe you have to look for a European Patent Attorney to submit a patent application.
How to apply for a patent in urgent cases In order to ease up the conflict of publishing vs patenting you can apply for a provisional US patent application.
A provisional US patent application is giving you an early and effective application day and provides a lower-cost first patent filing in US (official fees at the US Patent Office approx. US$ 400).
A provisional US patent application does not require to have a formal patent claim or declaration. It should not include any prior art because the provisional US patent application is not examined (no search report!). Within a 12 months period from the application day of the provisional US patent application a non-provisional patent application has to be filed.
A provisional US patent application can be done within 24hrs prior to publication, or talk, and one has one year to file a patent application in US or a PCT (Patent Cooperation Treaty).
