Patent Infringement Cannot Be Presumed

Bayer Corporation Vs. Union of India 162(2009) DLT 371

Bayer Corporation, instead of filing a suit for infringement, filed an inventive writ petition in the Delhi High Court desiring that since the applications of Cipla “SORANIB” allegedly infringed its patent, its (Cipla’s) marketing approval application under the Drugs Act should not even be processed or entertained. It is for the first time that an attempt is made to link drug approval to patent infringement in India. However, the Delhi High Court, denying the injunction, imposed a substantial cost of Rs. 6.75 Lakh to deter any such future attempts.

Bayer relied on the argument that a combined reading of Section 2 of the Drugs and Cosmetic Act along with Section 48 of the (Indian) Patent Act, 1970 establishes a Patent Linkage Mechanism under which no market approval for a drug can be granted if there a patent subsisting over that drug. It also claimed that CIPLA’s “SORANIB” is a “Spurious Drug” as defined under the Drugs Act, for which market approval cannot be granted.

The Hon’ble High Court of Delhi held that there is no Drug- Patent Linkage mechanism in India as both the Acts have different objectives and the authority to determine patent standards, is within the exclusive domain of the Controller of Patents. Moreover, the patent linkage will have undesirable effect on the India’s Policy of Public Health. It further held that the market approval of a drug does not amount to infringement of patent. Therefore, the patent infringement cannot be presumed, it has to be established in a court of law. Such adjudication is beyond the jurisdiction of Drug Authorities.

On the issue of “SORANIB” being a spurious drug, the court held that CIPLA’s “SORANIB” cannot come under the category of spurious goods as there is no element of passing off like deception or imitation present in CIPLA’s drug”.
