To obtain a valid patent, a patent application as filed must contain a full and clear disclosure of the invention in the manner prescribed by 35 U.S.C. 112(a). The requirement for an adequate disclosure ensures that the public receives something in return for the exclusionary rights that are granted to the inventor by a patent. All amendments and claims must find descriptive basis in the original disclosure. No new matter may be introduced into an application after its filing date. Applicant may rely for disclosure upon the specification with original claims and drawings, as filed. See also 37 CFR 1.121(f) and MPEP § 608.04.
If during the course of examination of a patent application, an examiner notes the use of language that could be deemed offensive to any race, religion, sex, ethnic group, or nationality, he or she should object to the use of the language as failing to comply with 37 CFR 1.3 which proscribes the presentation of papers which are lacking in decorum and courtesy. The inclusion of such proscribed language in a federal government publication would not be in the public interest. Also, the inclusion in application drawings of any depictions or caricatures that might reasonably be considered offensive to any group should be similarly objected to.
An application should not be classified for publication under 35 U.S.C. 122(b) and an examiner should not pass the application to issue until such language or drawings have been deleted, or questions relating to the propriety thereof fully resolved.
For design application practice, see MPEP § 1504et seq.
