Andreas Gutzeit Vs. Controller General of Patents

Andreas Gutzeit Vs. Controller General of Patents:High Court at Calcutta: Hon'ble Justice Ravi Krishan Kapur:15 May 2025: IPDPTA/7/2024

 

Facts:

The appellant, Andreas Gutzeit, filed an application for a patent titled "Blood Flow Control System and Method for In-vivo Imaging and Other Application" on January 1, 2016, based on an international application (PCT/CH2014/000151) claiming priority from Switzerland. The invention pertains to controlling blood flow during medical imaging, notably by using a respiratory resistance device to enhance image quality during procedures like CT scans.

Procedural Detail:

The Controller of Patents rejected the patent application on the grounds of non-compliance with Section 59 of the Patents Act, 1970, specifically regarding amendments to the claims that were alleged to broaden the scope of original claims or change the nature of the claims (method to system claim). The appellant challenged this rejection through an appeal before the Calcutta High Court.

Issue:

The core issue was whether the amendments made to the patent application, particularly the change from method claims to system claims, were permissible under Section 59 of the Patents Act, 1970, and whether the Controller’s rejection was justified?

Decision:

The Court held that the amendments, which broadened or altered the scope of the claims, were not permissible under the relevant statutory provisions. The Court set aside the impugned order, remanding the matter back to the Controller for fresh decision in accordance with law, ensuring proper opportunity for hearing. The Court emphasized that amendments should not expand the scope of claims beyond the original disclosure.

Andreas Gutzeit Vs. Controller General of Patents Case No.: IPDPTA/7/2024 Date of Order: 15th May 2025 Court: High Court at Calcutta  Judge: Hon’ble Justice Ravi Krishan Kapur 

Fact:

Mr. Andreas Gutzeit, an applicant for a patent titled “Blood Flow Control System and Method for In-vivo Imaging,” filed his application in India in 2016. The original claims primarily covered a method involving specific steps for medical imaging using respiratory resistance devices. During prosecution, the applicant amended his claims, converting method claims into system/device claims, intending to cover a broader scope. The Indian Patent Office (IPO) rejected these amendments, citing Section 59 of the Patents Act, which restricts amendments that expand the scope of the original claims. The applicant challenged the rejection in the Calcutta High Court.

Legal Issue:

Can amendments that convert method claims into system/device claims, supported by the original disclosure, be deemed invalid under Section 59 for broadening the scope of the patent?

Reasoning:

The Court reviewed principles of patent law concerning amendments, emphasizing that amendments should not extend the original scope. Narrowing claims or clarifying them is permissible, but widening claims that introduce new matter or claims outside the original disclosure is not. It clarified that if amendments are within the original disclosure, converting a method claim to a system claim does not inherently constitute broadening.The Court criticized the IPO’s rejection for not adequately assessing whether the amendments stayed within the original disclosure. It emphasized the need for a case-specific examination of amendments.

Decision:

The Court found the IPO’s rejection unwarranted, holding that the amendments did not violate Section 59. It set aside the rejection order and remanded the case to the Patent Office for re-evaluation, requiring a proper assessment of whether the amended claims remained within the scope of the original disclosure.
