What Do The Legal Statuses/Events Mean?

In PatSnap, you can filter by various different legal statuses/events to make sure you can see the right data.

PatSnap covers all the many different legal statuses/events, which you can also use to refine your search and make sure you see the data you are looking for.


Legal statuses

Take a look below to see the definition of each legal status:

Pending patents

Pending:  A patent application has entered the search and examination phases.

Published: A patent application was published. It is not a granted patent and it does not necessarily mean that the application will result in a patent.

Active patents

Granted: An application became a granted patent/patent in force.

Inactive patents

Invalid: Patent is invalid. There are different reasons why a patent is invalid:

  • Double: A patent right or utility model has been abandoned to avoid double patenting.
  • Discard: Patent right was abandoned.
  • D-Discard: An application deemed discarded. For example, no evidence of payment of the annual fees.
  • Withdraw: An application open to public inspection was withdrawn at the request of the applicant.
  • D-Withdraw: An application deemed withdrawn. For example, no reply to the examiner's opinion.
  • Rejected: An application is rejected by the examiner.
  • Revoked: Whole invalidation of a patent. A member of the public can question the validity of the patent, the grounds permitted for revocation are:
  • The invention is not a patentable invention.
  • The patent was granted to a person who was not entitled to be granted that patent.
  • The specification of the patent does not disclose the invention clearly enough to enable a person skilled in the art to make the invention.
  • The protection conferred by the patent has been extended by an amendment which should not have been allowed.
  • Expired: Patent term expired.
  • Non-payment: Non-payment of annual maintenance fees resulting in the invalidation of the patent.
  • Appeal: Appeal filed against an examiner’s decision.
  • Abandoned: The patent right has been abandoned.

Additional legal status

Interference: The patent is/was involved in an interference proceeding. An interference proceeding determines who is the first inventor and entitled to the patent when two or more applications are filed by different inventors claiming substantially the same patentable invention. (US patent office)

Legal events

Take a look below to see the definition of each legal event:

Transfer: Change in applicant/owner.

License: An exploitation case against a patent license contract has been submitted for record.

Pledge: A patent pledge agreement has been registered. Pledging a patent can be thought of like a mortgage for a house. This means for a patent that when the pledgor pledges the patent to the pledgee, the pledgee will gain ownership of the patent but they will have to pay the pledgor a regular fee. This is an alternative to paying for a full re-assignment since the pledgee might not want to pay the whole amount for the patent up front.

P-Revoked: Partial invalidity of the patent.

Opposition: A third party initiated an opposition proceeding to challenge the validity of a pending patent application or granted patent.

Trust: An entrustment of a patent from its owner to a trust company where the trust company finds a license destination of the patent and obtains income. According to our database, this appears to only be the case in Japan and Taiwan.

Litigation: A patent has been involved in a litigation case during its lifetime.

Re-examination: A patent has undergone a re-examination, which may result in it being invalidated, during its lifetime.
