JD: I saw a patent several years ago and now I can’t find it. I’m looking for the patent related to making jet fuel emissions transparent rather than black.

If you’re trying to find a specific patent and can’t locate it, one of the best places to look is Google Patents. They’ve done an incredible job categorizing patents, and you can filter by title, author, type of patent (whether it’s a design or utility), and the assignee (company name).

If you remember the company name, such as Boeing or GE or other manufacturers of jets, you can search by that assignee and then add in relevant terms related to emissions and the transparency of visible emissions.

Another resource is the USPTO ( They have a public search option, which in my opinion isn’t quite as robust as Google Patents, but it allows for more refined searches.

At our firm, we use a third-party search service that specializes in patent research. They utilize all the different classifications, whether it’s the US classification or International classification, to dive into the specific parts of the technology you’re interested in.
