Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

There is shown and described an improved acoustic hood for use with a
tractor feed attachment for a high speed printer or the like.
