All patents stated to be of pharmaceutical or veterinary interest, as well as those relating to compounds for use as intermediates in the manufacture of pharmaceutical or veterinary products.

Artificial sweeteners, chemical warfare agents and plaque disclosing compositions are also included.

Patents dealing with the production of tablets, pills, capsules, suppositories etc. are included, as are devices for dispensing pharmaceuticals such as - syringes, child-proof closures, calendar pill boxes, aerosols etc.

For each compound where more than one of the classifications given below could be assigned, then the order of priority is B1 before B2, B2 before B3.

B01 Steroids - including systems containing carbocyclic and/or heterocyclic rings fused onto the basic steroidal ring structure.
B02 Fused ring heterocyclics.
B03 Other heterocyclics.
B04 Natural products and polymers. Including testing of body fluids (other than blood typing or cell counting), pharmaceuticals or veterinary compounds of unknown structure, testing of microorganisms for pathogenicity, testing of chemicals for mutagenicity or human toxicity and fermentative production of DNA or RNA. General compositions.
B05 Other organics - aromatics, aliphatic, organo-metallics, compounds whose substituents vary such that they would be classified in several of B01 - B05.
B06 Inorganics - including fluorides for toothpastes etc.
B07 General - tablets, dispensers, catheters (excluding drainage and angioplasty), encapsulation etc, but not systems for administration of blood or saline or IV feeding etc.
