To this day I wonder if the trademark search site runs on Windows 98
I worked at a place for six months where I worked on an impossible number of projects that were hosted on Windows particularly including the really strange such as hosted on MS Access. (Something that could work pretty well or pretty poorly depending on how it was configured.)
I'd imagine trademark search would be easier and it looks like you can get that out of a data dump just like you can for patents.
The search engine used a neural network autoencoder for "more like this" queries and did a great job if you wrote a paragraph describing your invention and want to find related inventions, both in patent and non-patent literature. If it hasn't been made obsolete by Sentence BERT, however, it soon will be.

have to do with "three-sided cards"; these have many uses not least I can throw down several of them and take a picture to show on social media.
