FAQs Patent Questions

Question:How can I find out the inventor's name of a particular patent?

Answer:
Search may also be conducted at a Patent and Trademark Depository Library (PTDL) established throughout the United States. These libraries have copies of patents in multiple formats arranged in numerical order. They also have classification search tools, automated search aids, and photocopy facilities available to the public.

Question:The patent law specifies that its subject matter must be useful, meaning it is able to perform its intended purpose.

Answer:
The patent law specifies that the subject matter must be “useful.” The term “useful” in this connection refers to the condition that the subject matter has a useful purpose and also includes operativeness, that is, a machine which will not operate to perform the intended purpose would not be called useful, and therefore would not be granted a patent.

Question:Use of inventions more than one year prior to filling a patent will prohibit the granting of a patent

Answer:
Inventors are also reminded that any public use or sale in the United States or publication of the invention anywhere in the world more than one year prior to the filing of a patent application on that invention will prohibit the granting of an U. S. patent on it.
