The second article, which I'm afraid doesn't seem to be available online yet, and in paper only to members of the Litigation Section of the State Bar of Texas is an article in the Winter 2007 edition of the Section's quarterly publication The Advocate. That issue is a symposium issue entitled "Jurisdiction & Venue" and my contribution is the lead-off article "A Battle Over Where the War is to be Fought - Venue in Patent Cases", found at pages 10-13. It's a short article outlining the text and history of the current patent venue statute, with an analysis of the activity to date of the pending patent legislation. Luckily for me, nothing substantive has happened in Congress since I submitted the article, so for at least the next month or so, the article is fairly current.
The Litigation Section's new website is where to look for the article online when it is uploaded. I would also mention that the issue contains a good article on litigating before magistrate judges. I may post on that after studying it a little more.
Update: Here's a copy of the article - Download venue_in_patent_cases.pdf
