Was Edison a patent troll, and where is California going in stem cell research?

In March 2006, I had prepared an article for the April 2006 issue of Intellectual Property Today which discussed Thomas Edison's light bulb and stem cell research. I cited this article in my comments to the USPTO about proposed rulemaking in the area of continuing applications. Unfortunately for me, Intellectual Property Today didn't publish the article, either in April or May 2006.

Certain portions of that article have been placed in an ezine article,

Edison as a Patent Troll, or Where is California Going in Stem Cell Research?

[Of allegations that Edison did not make product, see an earlier IPBiz post about misstatements by Alan Murray of the Wall Street Journal.]
