Staying the Numbers: Damages Quantification and the Limits of “Exceptionality” after Lifestyle

/ By / Patent

The Delhi High Court’s decision to stay execution of a damages decree in M/s Pearl Engineering v. Koninklijke Philips N.V. raises uneasy questions about when money decrees can be put on hold. Aafreen Saraf argues that by relying on doubts in damages computation, the Court stretches the Supreme Court’s narrow “exceptional cases” standard reaffirmed in Lifestyle Equities v. Amazon Technologies. Aafreen is a third-year B.A. LL.B. (Hons.) student at the West Bengal National University of Juridical Sciences (WBNUJS), Kolkata. She

/ By / Patent

Recently, in Nippon v. Controller, the Delhi High Court intervened to rein in an unduly rigid view of proof of right adopted by the Patent Office. Explaining the judgement, Dipti examines how the Court dealt with proof of right, employer–employee ownership, and the premature invocation of Section 68, and what these moves mean for patent filing practice in India. Dipti is a penultimate-year student at Gujarat National Law University, Gandhinagar, with a strong interest in technology and intellectual property law.

The Unresolved Code: Anand Khosla, Arbitrability, and the Ghost of Rights in Rem

/ By / Copyright

In Anand Khosla v. Punam Kumari Singh, the Bombay High Court quietly retreats from the Supreme Court’s settled position on the arbitrability of IP disputes. Analysing the decision, Aditya Bhargava argues that it misapplies the rights in rem/personam distinction while considering the arbitrability of IP disputes under Vidya Drolia, and improperly legitimises the splitting of causes of action. Aditya is a fourth year law student at the National Law School of India University, Bangalore. [Long post ahead] The Unresolved Code: Anand

Patent professionals and researchers would know the pain of correctly identifying the final granted claims for an invention. Previously, one had to examine the written submissions and the amendments made by the applicant, along with the controller’s order, to identify the final granted claims post-examination. One can only imagine how difficult the same exercise would be for someone unfamiliar with Patent Office procedures and patent law in general.  To address this pain point and improve legibility of patent documents, the

One Chance or Two? Madras HC Bars LPAs in Patent Disputes, Deepening High Court Parity

/ By / Patent

How many chances do you really get to appeal a rejected patent application? Recent High Court decisions on the maintainability of Letters Patent Appeals suggest that the answer may depend less on law and more on geography. Taking a look at the conflicting High Court rulings on Letters Patent Appeals, Hruthika Addlagatta explains how the conflicting opinions have turned appellate access into a jurisdiction-dependent question, raising serious concerns of equality and fairness. Hruthika is a second-year law student from NALSAR

Natural Justice Without Participation? Patent Examination, Civil Consequences, and the Zydus Judgment

/ By / Patent

The Delhi High Court in Zydus v. Controller of Patents has reaffirmed a formal separation between patent examination and pre-grant opposition, characterising examination as a self-contained, non-adversarial process. While this approach emphasises procedural efficiency, it raises deeper questions about how natural justice operates once a pre-grant opposition is on record. Arshiya Gupta and Reyansh Khandelwal critically examine whether the Court’s insistence on formalism comes at the cost of substantive fairness in patent prosecution. Arshiya is a third-year law student at
