Factors for patentees to consider when deciding where to file patents internationally:

  • Where the patentee and/or potential infringers have a presence (patentee has best knowledge)
  • Patentee’s business strategy regarding patents (patentee has best knowledge)
  • Standards of patentability in the jurisdiction for invention subject matter (help needed from IP or other expert)
  • Restrictions on patent rights within the jurisdiction for invention subject matter (help needed from IP or other expert)
  • Degree of enforceability in the jurisdiction (help needed from IP or other expert)
  • Process, cost, and timeline to apply for and obtain a patent in a particular jurisdiction (help needed from IP or other expert)

The relative importance of the above factors will depend on patentee’s business plan and goals.
