more GE food, and the Bt patent fight



Here are a couple of articles I thought this group might be interested 
in - the scope of GE'ed foods and the patent circus.  Their positive 
tone is not mine.

>LITIGATING BT PATENTS FOR MARKETSHARE
>A recent (1/23/97) press release headline states,  Mycogen
>Corporation has filed suit in Federal Court here [San Diego],
>claiming that a new bioinsecticide developed by Ecogen Inc. infringes
>Mycogen patents covering Bacillus thuringiensis (Bt) gene
>technology.  There have been so many lawsuits in recent years over
>claimed infringements relating to Bt that even industry insiders who
>keep a close watch on these activities have a hard time keeping
>track of who is suing whom. It s not just the Bt genes themselves,
>but every aspect of the technology relating to Bt genes, including
>the promoters, selectable markers, full-length versus truncated and
>synthetic versions, transformation methods, etc. The following table
>which lists recent suits is incomplete, but it provides a sense of
>the intensity of the battle over the patent claims relating to Bt.
>The fact that litigation is extremely expensive and time consuming
>suggests that the stakes are high for the participants.

>These disputes are to be settled in court. Why can t the companies
>sit down at a table and find an amicable solution? Depending on who
>you ask, the following answers are given:
>
>
> These disputes reflect the novelty of this technology to the
>  seed industry. The situation is reminiscent of the learning
>  process which the chemical and pharmaceutical industries went
>  through in past years.
> There is much at stake financially because the new technology
>  generates a lot of added value and all the players believe they
>  are entitled to a big piece.
>
> Extended litigation saps the financial resources of weaker
>  companies, assisting in further consolidation of agbiotech
>  companies, to the advantage of the financially stronger
>  companies even though their patent claims might be weaker.
>
> There is a lot of pressure on companies to maintain their stock
>  value which is partially based on claimed property rights.
>
> Some of the players have big egos. Monsanto's CEO Robert Shapiro
>   will kick butt in the marketplace  in order to  get
>  environmentally better products that people want to market
>  faster at lower costs  (Fortune 4/16/96, p116).

>The good news is that, in spite of the litigation, corn, cotton, and
>potato modified with the Bt gene technology are being aggressively
>commercialized. Several companies have already brought products into
>the market place. There are many examples of research collaborations
>and licensing agreements which allow other interested parties access
>to the patented materials. DeKalb, for example, recently announced
>that  Monsanto s acquisition of Holden s Foundation Seeds will have
>no impact on the long-term research collaboration or the cross-
>licensing agreements that DeKalb and Monsanto entered into a year
>ago.
>
>On the negative side, farmers, who will benefit from the new
>technology through reduced pesticide use and increased yield, will
>likely pay the price of the lawsuits in the cost of the value-added
>seed. Another negative impact, according to Brent McCown (University
>of Wisconsin), is that commercialization of genetically modified
>minor crops has been prevented or delayed due to conflicts over
>proprietary rights. For example, commercialization of Bt-cranberry
>has been put on hold until some of the Bt patent issues are settled.
>The small cranberry industry is not willing to commit the necessary
>resources - time and money for lawyers - to pursue the necessary
>agreements in the uncertain environment created by the numerous
>lawsuits.
