There are a lot of OCR errors in Google Patents, which may contribute
to the effect you describe.

When found, the title is spelled correctly on the patent pdf itself,
but incorrectly in the patent title description on the search engine.
However it could be a flub on Google's part also, as you say.
In one case I noticed a "B" had been transposed for a "R", which could
happen if they were optically scanned and the software misidentified a
letter.
