Supported Cases

In today’s rapidly evolving technological and industrial landscape, patents provide inventors with the means to protect and commercially leverage their innovations. However, the rights granted through patent registration can be challenged and potentially invalidated under certain circumstances. 

A patent may be deemed invalid if it can be demonstrated that the invention fails to satisfy the essential criteria required for patentability. Determining the possibility of invalidating a patent involves conducting a thorough patent invalidity review, which assesses whether the patent meets all legal and technical requirements for protection.

  • Detailed technical examination of the subject of the invention
  • Determination of the conditions under which invalidity is possible
  • Comparison of the existing arguments and the invention to be invalidated

SIMAJ is able to provide consultancy services to its clients regarding the legal and administrative processes that may arise in this field.
