AI發明涉及的議題主要有兩個：inventorship以及eligibility。
Inventorship：
35 U.S.C. 100(f) - The term “inventor” means the individual or, if a joint invention, the individuals collectively who invented or discovered the subject matter of the invention.
法院意見是，發明人必須是"自然人"，另有議題是：AI輔助的發明是否為可專利標的？目前的意見是，發明人仍應該是自然人，而在此議題下，則必須是對發明具有實質貢獻（"significantly contributed to the invention"）的自然人可為發明人或共同發明人。其中判斷運用了Pannu factors，發明人必須滿足三個Pannu factors。
引用案例：
- A.I.不能是發明人；或說發明人不能是非人類 - Thaler v. Hirshfeld, App No. 21-02347 (Fed. Cir. 2022)（https://enpan.blogspot.com/2023/04/ai-thaler-v-hirshfeld-app-no-21-02347.html）
- 專利申請中新增的特徵產生共同發明人爭議 - Pannu v. Iolab Corp. (Fed. Cir. 1998)（https://enpan.blogspot.com/2023/05/pannu-v-iolab-corp-fed-cir-1998.html）
Pannu factors:
(1) contributed in some significant manner to the conception of the invention;
(2) made a contribution to the claimed invention that is not insignificant in quality, when that contribution is measured against the dimension of the full invention; and
(3) did more than merely explain to the real inventors well-known concepts and/or the current state of the art.

重點：
– Use of AI-based tools by practitioners and parties is not prohibited
– Practitioners reminded of existing rules that may be relevant to use of AI-based tools
– Notice educates practitioners on possible risks associated with AI-based tools to promote healthy adoption of AI in practice before the USPTO
– USPTO’s existing rules and policies help mitigate risks of AI assistance
– Guidance does not introduce any new rules or duties
