Yes, it is possible Matt, but not as straightforward as searching with the patent number itself. It used to be easier, but the German Patent Office has kept refining the system and has aimed it more at the expert searcher rather than the beginner. I haven't kept up with these changes and would need several hours reading all the guide notes to get where I was 10 years ago.
Anyway, this is what you can do. Go to the beginners search page, English version, here :
https://depatisnet.dpma.de/DepatisNe...witchToLang=en
Then in the box "All Classification Fields" insert F41B 11/00. This directs the search to the patent classification covering air guns. In the box "Application/ Owner/Inventor' insert the name of the inventor (or company). This is where it can get tricky, as it has to be in the right format. For example, Mayer and Grammelspacher will be rejected, Mayer accepted. You need to read the guide notes if it will not accept your entry.
Then click Search and you should get a list of all air gun patents from that person or company. Annoyingly, although the seach will cover patents from many countries, there is no way of restricting the search to just one country (unless you use the Expert search option). When the search sometimes throws up a couple of thousand hits, it would be helpful if you could narrow things down a bit.
Good luck!
Cheers, John
