Patent Marking

Patent Pending

  • The "patent pending" notice means a U.S. patent application has been filed.

  • The "patent pending" words can (and should) be displayed as soon as a U.S. patent application is filed.

  • The patent application can be a non-provisional utility patent application, provisional patent application, design patent application or plant patent application.

  • The "patent pending" notice is a warning that a patent application has been filed, and that a patent might be issued from such patent application. 

see provisional vs non-provisional patent applications, patent applications

Patent Number

  • Patented products (articles) sold or offered for sale should be marked with the U.S. patent number.  This marking is simply the word "U.S. Patent" or "patent" or abbreviation "pat." followed by the patent number.

  • This marking should be "fixed" to the product by molding, engraving etc. methods.  When, from the character of the product, this cannot be done, a label bearing the marking should be placed on the product or packaging.

  • Patent marking permits the patent owner to seek monetary damages (in addition to injunctive relief) in a patent infringement action without proof that the infringer had actual notification of the patent.

  • In addition, the public notification in and of itself might avert infringement issues.
