This chart shows the drug companies with the most supplementary protection certificates (SPCs).
SPCs are used in European Union and select others to encourage pharmaceutical innovation by
compensating for the long time needed to obtain regulatory approval for drugs. SPCs
come into force only after the corresponding general patent expires, and normally have a maximum lifetime of 5 years.
The total combined duration of market exclusivity of a general patent and SPC cannot normally exceed 15 years, but a six-month extention
may be obtained by responding to a request for pediatric trials.
The pharma companies with SPCs in the most countries are:
- Astrazeneca
- Bayer
- Glaxosmithkline
- Abbvie Inc
- Astellas
- Boehringer Ingelheim
- Bristol-myers Squibb
- Gilead Sciences Inc
- Janssen Prods
- Merck Sharp Dohme
