1) An application for a patent, published under §122(b), by another filed in the US before the invention by the applicant, except that the international application filed under the treaty … shall have the effect under this subsection of a national application published … only if the international application designating the US was published … of such treaty in English; or

  • IA was filed on or after 11/29/00; the IA designated the US; and published in English
  • US Application Publications – is prior art of the application’s US effective filing date, which can include an IA filing date, if it meets above 3 conditions

Key to remember:

1. Publication of application / Grant of Patent in the US

2. Of ANOTHER

3. BEFORE your own invetion

It is more with effective filing date

Any pending applicaiton of ANOTHER becomes a Patent or Publicaiton of it

AFTER filing of YOUR application

Filing date of earlier applicaiton of ANOTHER becomes a bar for your application under 102(e) = can be any date – must be priot to your filing date application

Mary conceived an invention on 2.27.1993 and RTP on 8.20.1993. She filed a provisional application on the invention on 3.14.95 and a utility application on 3.13.96 which claimed the priority right of the provisional application. The invention was disclosed, but not claimed in a U. S. patent to Wilson which was filed on 5.13.95, issued 6.14.97, which is a proper continuation of an application filed in the US on 7.5.1992. Which paragraph, if any, of 35 USC 102 applies?

The answer is 102 e. My question is “does 102 a or b also apply?”

I thought it is prior to your date of invention and not the filing date of application. Is that correct?

help me understand this PLI hypo:
X RTP invention A in Belgium on June 25, 1992 and later filed a US application on January 14, 1994. Claims of Invention A were rejected as being anticipated by the disclosure in a US patent to Y. Y’ patent issued on August 16, 1994 and is based on a patent application filed on June 26, 1992. Under which of the following 102 sections would X NOT be entitled to a US patent?

I don’t understand why the answer is 102e. is it because the Date of Invention cannot be relied due to the activities being in Belgium? If so, why wouldn’t 102a work as well?

The reason why you can’t rely on the belgium filing for priority is because of the date that it was filed. In 1992 Belgium was not available as a WTO member. A date of completion of the invention may not be established under 37 CFR 1.131 before December 8, 1993 in a NAFTA country or before January 1, 1996 in a WTO country other than a NAFTA country. Therefore, since you can’t rely on the belgium filing for priority the filing date of Patent Y is 102e prior art.

Remember that 102(a) relates to date of publication (also public knowledge in US, etc.) and not date of filing.

Hope this helps!

Isn’t it also true applications of 1992 were not published unless requested. Since it was not noted in the question, wouldn’t we assume that the application was not published until it issued in 1994. Therefore, to use a date before 1994, we would need to use 102e?
