E-DRUG: E-DRUG: Patent expiry dates?  
------------------------------------

You should be able to find the list of some drugs going off patent by 2005  
from Orange Book at \< [http://www.fda.gov/cder/orange/19bookpub.pdf&gt](http://www.fda.gov/cder/orange/19bookpub.pdf&gt); for US  
and the Canadian Patent Register (for Canada) at  
\<[http://www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/patents.html&gt;\](http://www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/patents.html&gt;%5C).

Hope the above will help.

The FDA publishes an Orange Book which contains all the information about  
Drugs registered in US. [http://www.fda.gov/cder/ob/](http://www.fda.gov/cder/ob/) The book has an annex  
which lists patent and exclusivity information. This is an Adobe Acrobat  
file and is available at [http://www.fda.gov/cder/orange/19bookpub.pdf](http://www.fda.gov/cder/orange/19bookpub.pdf)

This is useful information for the US and for US registered companies.

quite powerful! WB]
