I learned yesterday (via Vincent McBurney's blog) that the infamous "ETL patent" (technically, patent 6,195,662 - System for transforming and exchanging data between distributed heterogeneous computer systems) is being re-examined by the U.S. Patent Office. The examiner intends to withdraw essentially all of the claims.
It's a bit tricky to get information about this from the USPTO web site, and it's not possible to link to much of its content. If you want to look, here are the necessary steps:
- Go to the Public PAIR start page, type in the captcha, and click "continue".
- In the "search for application" panel, make sure the top radio button is selected ("Application number"), enter 90/011267 in the box, and click "search".
- Click on the "Image File Wrapper" tab. You'll then see a list of documents associated with the application. You may want to look at Reexam proceeding - Advisory Action, dated 06-07-2011, 9 pages. It states the intent to withdraw claims 1-11 and 14-19.
