1. The Summary was generated by Gemini (https://gemini.google.com/) after a brief chat about patent citations using a prompt generally as follows: 'Assume you are a person of ordinary skill in the art in the field of: [WIPO field]. Write a short article. Topic: an industry cheerleading informative overview of the most cited patents by patents issued in 2023 in that field. Use the list of patents below, which list includes the US patent number, title, and inventors of the most cited patents by patents issued in 2023 in that field. Include inventor names, patent numbers and patent titles to support the positions and statements made in the memo. Assume these most cited patents teach and disclose foundational knowledge and thus indicate areas receiving the most attention in this field in 2023. Include hashtag terms that are pertinent and will target decision makers in the market to buy attorney IP services.' followed by the list of patents relating to that WIPO field. (The list of patents had been previously generated through other means.) Gemini's output was edited, removing redundant content and topics outside the scope. As such, the statements in the Summary do not necessarily reflect my own views, and are NOT intended as legal, financial, or any other type of advice.
