The same is true of patents. Apply in time and keep it confidential before application. The patent claim must be written when applying, which is the key to whether a patented technology can be protected most effectively.
After obtaining intellectual property rights, we should protect our rights in time. Including the monitoring of their own trademarks, the maintenance of patent rights of patented products and so on.
2. The principle of universal coverage.
Comprehensive coverage means that the accused infringer (product or method) reproduces all the necessary technical features of the technical scheme recorded in the patent claim, and the accused infringer (product or method) corresponds to and is the same as all the necessary technical features recorded in the patent independent claim. The principle of universal application is one of the most basic principles for judging patent infringement.
3. The scope of patent protection of invention or utility model shall be subject to the contents of its claims, and the description and drawings can be used to explain the claims.
First of all, you should find a notary office to accompany you to buy infringing products and notarize them, which can be used as evidence in future infringement lawsuits.
In addition, instead of litigation, you can negotiate with the infringer, sign a patent license contract or a patent transfer contract, and ask him to pay the patent fee and compensate the infringement loss reasonably.
