Microsoft Is Sued For Patent Violation Over .NET
randomErr writes "As reported by Info World, Microsoft was issued a cease and desist order on February 7 of this year by Vertical Computer Systems. The order was for patent infringement by the current implementations of the .NET framework. Both the .NET framework and Vertical Computer Systems' SiteFlash use XML to create component-based structures that are used to build and operate web sites. Vertical Computer Systems is requesting a full jury trial. If VCS prevails, .NET technology implementations as we know them may completely change and Microsoft would probably have to pay out a hefty sum."
I'm a former employee of a certain large software company related to TFA, and interestingly, one thing they tell you when you go to work there (and I suspect other large companies that file lots of patents also do this) is that you should not - never, ever, ever - do any research into patents to try and find out if something you're developing or have developed and may be filing a patent application on might infringe any existing patents.
The reason for this is that if you do, infringement becomes easier to prove for anyone who does happen to sue you, because they can point at you and say "See, these programmers did patent research in this area, then produced a product and/or filed a patent on stuff that does what my stuff does" and if they win, then they will do better in the damages phase because they can present evidence showing willful infringement.
The bottom line was, leave any patent research, including the decision of whether or not to do it, up to the legal department. Don't get anywhere near it yourself.
As another ex-examiner I agree with the points you have made. I took a quick look at the prosecution of this application. There were three non-final rejections made before the application was allowed. The examiner spent a good deal of time in laying out rejections under 35 USC 102 (anticipation) and 35 USC 103 (obviousness), using a two column format with the claim limitations in the left column and relevant sections from the prior art in the right column. The applicant made essentially no substantive changes to the claims and just asserted that examiner didn't show what was asserted. I think the examiner made a big mistake in the second and third rejections of failing to respond to the arguments made by the applicant in the amendments; this was noted by the attorney in the last amendment after which the application was allowed.
There are three things one must keep in mind in figuring out exactly what is covered by a patent. Fundamentally it is the claims that measure the invention, not the title or abstract, or random pieces of the specification. However, the language and terms in the specification must be interpreted in light of the description given in the specification. So, if a term in a claim is an "object library", for example, it wpould be interpreted as this term is discussed in the description. Finally, and relevant to the failing pointed out in the previous paragraph, the scope of the claims is further qualified by the back and forth of the comments and arguments made by the examiner and the applicant. If the applicant tries to avoid a rejection by arguing that a prior art reference feature is not covered by some limitation in the claim the applicant will be bound to this interpretation in any infringement action should a patent be issued. One of the purposes of making rejections, even if it might not be spot on a limitation is to flush out and clarify such possible ambiguities. This is particularly applicable here where an examiner decides to allow a claim previously rejected with no further limitation added. If an applicant is going to squeeze through a narrow "hole" in the prior art not coverable by an obviousness rejection it is important to make sure it is as narrow as possible. By failing to engage the attorney's arguments in the following rejections here the examiner weakened this aspect of prosecution. Instead it looks pretty much like set arguments back and forth, with the examiner essentially saying "OK, I give up, you win" with no further comment.
Fianlly, I see that a continuation has been filed, but, so far, has been stripped to just claim 1 of the issued patent (with one misspelling). There will clearly be a preliminary amendment filed with claims applicant wants to prosecute, but have no idea what this might be.
