The issues under Indonesian Patent Law, assuming there is a legitimate Prior User ‘A’ rights are:
- to be able to continue such prior use of such invention even if the patentee ‘B’ is granted a patent in Indonesia even if the priority date is earlier (even if ‘B’ has filed anywhere else in the world before this prior use date. Referred to in Article 13).
- ‘A’ has no rights to claim prior use if ‘A’ has used knowledge derived solely from ‘B’s patent published or disclosed anywhere in the world (Referred to in Article 14)
- ‘A’ must submit a patent application to the Director of Patents in Indonesia after ‘B’ patent has been issued.
Prior user rights in Indonesia allow non-patentees to continue using their inventions in the same right as they had been before a patent on that same idea issued to ‘B’ and it shall expire at the same time as the expiry of ‘B’ Patent.
Article 13 (1) further implies that ‘A’s prior use is meant to give protection to ‘A’ with good faith but ‘A’ did not make an Application for patent.
- under the current Patent Law, the procedure for ‘A’ to obtain the recognition as a prior user is yet to be regulated by Law. The Patent Office is unable to give such recognition and will probably leave it pending until the issuance of said Regulation. Meanwhile, it is questionable if 'A' can continue with 'A's prior use while 'A's application is still pending.
- based on the information from the Registry, the request for obtaining the certificate as prior user is rarely filed due to the above reason, in addition to the administrative reason that such request shall be furnished with the evidence that the exploitation of said invention was not performed using any information on the invention for which a patent has been requested.
- the prior use claimed by ‘A’ must be only in Indonesia and if ‘A’ has prior use in India (for example) than this is not considered prior use.
- "A" cannot license the prior user rights unlike 'B' who’s granted patent can be licensed to multiple parties non-exclusively.
