Intellipharmaceutics International Inc. (IPCI)

[Samsa]

IPCI files its answer to lawsuit! they deny allegations. allege the Purdue patents are unenforceable and invalid. They point out that IPCI has filed an NDA not a generic ANDA. they counter sued Purdue ! asking for legal fees and court costs as well as for summary dismissal of the suit. they also point out that Purdue should be "estopped" (meaning barred) from being able to enforce the patents as outlined in law when issues of patent invalidity are raised and therefore asking that the court to bar Purdue and all others from stopping the FDA or from hindering the FDA from the approval process.

thats pretty much in a nut shell. its a 48 page document that they go line by line answer the plaintiffs charges.
