Patents with small molecules filter

The filter aims to return only the patents that are more likely to contain small molecule compounds. It is derived from the work of Falaguera and Mestres (2021).

More precisely, it makes use of the CPC/IPC codes that are used to hierarchically classify the patents.

Patents are returned only if their CPC or IPC classifications contain ANY OF:

- A61K0031 (Medicinal preparations containing organic active ingredients)

- A61K0033 (Medicinal preparations containing inorganic active ingredients)

- A61K0045 (Medicinal preparations containing active ingredients not provided for in groups A61K 31/00-A61K 41/00)

- A61P (specific therapeutic activity of chemical compounds or medicinal preparations)

But NOT any of the following:

- A23 (Foods or foodstuffs; their treatment, not covered by other classes)

- A24 (Tobacco; cigars; cigarettes; simulated smoking devices; smokers' requisites)

- A61F (Filters implantable into blood vessels; prostheses; devices providing patency to, or preventing collapsing of, tubular structures of the body, e.g. stents; orthopaedic, nursing or contraceptive devices; fomentation; treatment or protection of eyes or ears; bandages, dressings or absorbent pads; first-aid kits)

- A61G (Transport, personal conveyances, or accommodation specially adapted for patients or disabled persons; operating tables or chairs; chairs for dentistry; funeral devices)

- A61H (Physical therapy apparatus, e.g. devices for locating or stimulating reflex points in the body; artificial respiration; massage; bathing devices for special therapeutic or hygienic purposes or specific parts of the body (electrotherapy, magnetotherapy, radiation therapy, ultrasound therapy))

- *A61K0007 (Cosmetics or similar toilet preparations)

- A61K0008 (Cosmetics or similar toilet preparations)

- A61K0009 (Medicinal preparations characterised by special physical form)

- A61K0036 (Medicinal preparations of undetermined constitution containing material from algae, lichens, fungi or plants, or derivatives thereof, e.g. traditional herbal medicines)

- A61K0038 (Medicinal preparations containing peptides)

- A61K0039 (Medicinal preparations containing antigens or antibodies)

- A61K0045 (Medicinal preparations containing active ingredients not provided for in groups A61K 31/00-A61K 41/00)

- A61K0047 (Medicinal preparations characterised by the non-active ingredients used, e.g. carriers or inert additives; Targeting or modifying agents chemically bound to the active ingredient)
