Share of Large Pharmaceutical Enterprises in Nanotechnology Innovation

According to Statnano, three enterprises Sanofi, Novartis, and Pfizer possess the first three ranks in the number of nanotechnology patents among top enterprises presented by Forbes. Also, there are 18 enterprises from the United States among the 42 top enterprises. The United States possesses the first rank and Japan and Switzerland have the second and third rank, respectively.

Nanotechnology has many applications in various sciences as an intra-major technology, and many industries have adapted nanotechnology in the recent years. Pharmaceutics is one of the industries to invest a lot in the application of nanotechnology. Large pharmaceutical enterprises are usually very important at international level and they possess significant share among the leading enterprises all over the world. Depending on the importance of nanotechnology to the enterprises, all of them have allocated a part of their innovation and patenting to this novel technology. Patents are one of the important indicators in order to study the trend of nanotechnology penetration into pharmaceutics industry and its effects.

The list of leading enterprises presented by Forbes has been used in order to find leading enterprises in the field of pharmaceutics, and Orbit Databank to gather the number of patents have been published or granted until 30 July 2013 by those enterprises.

Table 1 lists the names of 42 pharmaceutical enterprises that have the highest number of nanotechnology-related patents (sum of granted patents and published patent applications). Three enterprises Sanofi, Novartis, and Pfizer possess the first three ranks in the number of patents in the field of nanotechnology.

Figure 1 demonstrates the share of countries in this ranking. There are 18 enterprises from the United States among the 42 enterprises listed in Table 1. The United States possesses the first rank and Japan has the second rank by having six enterprises. Figure 2 shows the classification of the enterprises according to their continent. As is seen, continents America, Europe, and Asia rank first to third while there is no enterprise from Africa or Pacific.

According to information obtained from Orbit Databank, during 2001-2005, the highest number of nanotechnology-related patents has been registered by the enterprises, which is a sum total of 2387 patents.

Figure 4 demonstrates the ratio of nanotechnology-related patents to all patents of different enterprises. As is observed in Figure 4, Safoni, Novartis, Merck, Pfitzer, Amersource Bergen, and Roche Holding enterprises are placed at upper right side of the chart, which is an indicator for having high number of patents and nanotechnology-related patents at the same time. It expresses that the abovementioned enterprises are among the leading enterprises in all fields of science and technology.

Another indicator in this research is the ratio of nanotechnology-related patents to all patents (patent portfolio) of the enterprise. This indicator expresses the role of nanotechnology and its effect in the general strategy of the enterprise. As is seen in Table 1, Aphios Co. has the highest share of nanotechnology-related patents (29.41%). Although this enterprise has registered only 34 patents, almost one-third of its patents are related to nanotechnology. One of the approaches of the enterprise is the application of nanotechnology in the production protein nanoparticles, polymeric nano-spheres, and nano-phospholipids for drug delivery modification in order to increase health, to prevent diseases, and to cure some types of cancers, infectious diseases, and malfunctions in central neural systems such as Alzheimer. About 10% of patents of SkyePharma Co. are related to nanotechnology too.

Although the number of patents registered by large pharmaceutical enterprises seems to be acceptable in the field of nanotechnology, the ratio of their nanotechnology-related patents to all patents is rather low. This fact proves that the use of nanotechnology in pharmaceutical applications is a new approach. Figure 5 demonstrators top 15 pharmaceutical enterprises in the ratio of nanotechnology-related patents to all patents.

Figure 6 demonstrates the share of leading pharmaceutical enterprises in alive and dead nanotechnology-related patents. About 68% of nanotechnology-related patents registered by leading pharmaceutical enterprises are alive and are legally protected while 32% are dead and there is no protection for them. The figure shows that acceptable percentage (about two-third) of patents in this field is legally reliable and protected.
