Try using this Subject Heading to find any books on the History of the Paris Convention
The easiest thing to do here would be to look for one U.S. case and then search the foreign law database vLex, as well as the Encyclopedia of Laws and Westlaw/Lexis/HeinOnline and Bloomberg Law (especially their World Intellectual Property Report™) for a legal news article or a scholarly article about a relevant case. It is practical to also check Google Scholar, but Westlaw and Lexis & Bloomberg Law will allow you to do the most precise searches. eg. "Paris Convention" /5 10bis.
Where on Westlaw or Lexis you would search for the word Paris within 5 words of the term 10bis by typing Paris /5 10bis, on HeinOnline, you must type "Paris 10bis"~5
Also try searching the indexes below for the terms Paris and 10bis. (Don't worry, indexes are just another kind of database that mostly contains citations rather than full-text.)
