News item on Schering-Plough today says that SP is expecting that a new patent to be issued on Intron A will extend its patent protection another twenty years after its original expiration date in 2001.

Peg Intron A was not mentioned in the news release since the patent will issue from the original Intron A formulation not PEG Intron A.

Its hard to read what impact, IF ANY, this might have on ENZN. One of the pluses for PEG Intron was the potential that the Intron A could extend its patent life based on the PEG formulation. Does SP need PEG Intron now????? Will the new economics of Intron A (why pay royalties to ENZN)force ENZN to the sidelines??

On the plus side, the formulation benefits of PEG Intron, and there appear to be several, would make PEG Intron A a very formitable force in its market. SP is almost to the finish line with FDA approval for the PEG version. The question now could be will they market it.

Any comments??
