Patent Searching For New Inventors - Searching By Keyword

If you use two keywords you have to decide how you want the search engine to treat the two words.

AND

In the example above, I wanted to find inventions that had both the words puzzles AND jigsaw in the patent. I selected AND in the drop-down menu.

OR

When you select OR in drop-down menu, you would find inventions with either the words puzzles OR jigsaw in the patent.

ANDNOT

If you select ANDNOT in drop-down menu, you would find inventions with the word "puzzles" in the patent ANDNOT the word "jigsaw" in the patent.
