Can I use my own terminology in the detailed description of my patent application?

Yes, you can generally use your own terminology in the detailed description of your patent application. The MPEP 608.01(g) states:

“An applicant is ordinarily permitted to use his or her own terminology, as long as it can be understood.”

However, there are some important considerations:

• The terminology must be clear and understandable to a person skilled in the relevant field.
• Consistency is key – use the same terms throughout your application to avoid confusion.
• If you introduce new or unconventional terms, it’s advisable to provide definitions or explanations.
• The examiner may require grammatical corrections, but this is not the primary focus of the examination.

Remember, while you have flexibility in your terminology, the ultimate goal is to clearly communicate your invention. If your unique terms hinder understanding, it may be better to use more standard language in the field.
