Since 1918, the Journal of the Patent and Trademark Office Society has been a medium of expression for the exchange of thought in the fields of Patents, Trademarks, and Copyrights; a forum for the presentation and discussion of legal and technical subjects relating to the useful arts; and a periodical for the dissemination of knowledge of functional attributes of the patent, trademark, and copyright laws, in order to effect a more uniform practice thereof and through which all interested in the development and appreciation thereof may work to a common end. The Journal is published quarterly by the members of the Patent and Trademark Office Society. Also, the Blog is maintained and updated on a regular basis by the members of the Patent and Trademark Office Society.
