Weatherford U.S., L.P. successfully petitioned the PTAB to challenge Halliburton Energy Services' patent (11333007) regarding wellbore gravel packing technology. The Board granted institution, finding a reasonable likelihood of prevailing on obviousness grounds (§ 103).
Apple Inc. v.Resonant Systems, Inc.
Apple Inc.'s IPR challenge against Resonant Systems, Inc. was instituted after the Board found a reasonable likelihood of prevailing on at least one claim.

Zhejiang Lingdi Digital Technology Co., Ltd. v.CLO Virtual Fashion, Inc.
The PTAB denied Zhejiang Lingdi Digital Technology's IPR challenge against CLO Virtual Fashion, Inc.'s virtual clothing measurement patent. The Board found no motivation in the prior art (Grinspun and Graphicxtras) to combine them to achieve the claimed method of measuring 2D patterns with separation awareness.
Zhejiang Lingdi Digital Technology Co., Ltd. v.CLO Virtual Fashion, Inc.
The PTAB denied the institution of an IPR challenging CLO Virtual Fashion's digital clothing patent (10,733,773) after finding that the petitioner failed to demonstrate a reasonable likelihood of success. The Board rejected the obviousness arguments based on impermissible hindsight and unsupported expert testimony.
Zhejiang Lingdi Digital Technology Co., Ltd. v.CLO Virtual Fashion, Inc.
The PTAB denied the IPR petition filed by Zhejiang Lingdi Digital Technology Co., Ltd. against CLO Virtual Fashion, Inc.'s patent 11,410,355, finding that the challenger failed to demonstrate a reasonable likelihood of success on obviousness grounds.

Nokia of America Corporation et al. v.Iarnach Technologies Limited
Nokia of America Corporation successfully petitioned the PTAB to challenge Iarnach Technologies Limited's patent (9806892) on grounds of obviousness in passive optical networks (PON). The Board found a reasonable likelihood of unpatentability for several claims based on combinations of prior art references.
Nokia of America Corporation et al. v.Iarnach Technologies Limited
Nokia of America Corporation et al.'s IPR petition against Iarnach Technologies Limited was denied by the PTAB, preventing trial on claims 1-11. The Board found that the combination of prior art references (G.984.3 and Khermosh) did not sufficiently teach or suggest the claimed method for managing upstream burst overhead parameters in PON systems.
WEATHERFORD U.S., L.P. et al. v.Halliburton Energy Services, Inc. et al.
The PTAB issued a Final Written Decision finding several claims unpatentable based on obviousness (103). Specifically, claims 11, 12, and 14–20 were found obvious over combinations of prior art references. The Board also denied the Patent Owner's motion to amend regarding substitute claims 29-37, rejecting some for lack of enablement/utility.
Apple Inc. v.Resonant Systems, Inc.
The PTAB found the claims unpatentable under 35 U.S.C. § 103, specifically regarding vibration-generating devices. The Board concluded that a Person of Ordinary Skill in the Art (POSITA) would have been motivated to combine prior art references like Alexander and Cosper to achieve the claimed results.
Nokia of America Corporation et al. v.Iarnach Technologies Limited
The PTAB found several claims of the patent unpatentable based on obviousness over combinations of prior art standards (G.987.3, G.988) and publications (Röger). The Board specifically determined that Claim 1 was obvious because the combination suggested direct transitions between low-power states for increased energy efficiency.

M/S Nakoda Food Marketing & Ors. v.M/S Mahesh Edible Oil Industries Limited
The Delhi High Court addressed an application filed by the respondent seeking interim relief in a trademark dispute. The court noted that while the respondent's mark is registered and well-known, the appellants' mark was unregistered and had previously been withdrawn from registration. Consequently, the court declined to grant any ad interim order at this stage but directed the appellants to file detailed documentation regarding their prior use and application history for future consideration.
Ds Agrifoods Private Limited v.M/S Singhal Enterprises & Ors.
The Delhi High Court granted an ad-interim ex-parte injunction in favor of Ds Agrifoods Private Limited against M/S Singhal Enterprises & Ors. The court found that the Defendant's use of the mark 'DOODMALAI' and its associated trade dress was deceptively similar to the Plaintiff's established trademark 'DOONMALAI'. Given the phonetic, visual, and structural similarity, coupled with a prior business relationship suggesting bad faith, the court ruled that the Defendants were passing off their goods. This interim order protects the Plaintiff's market standing until the final hearing.

The Delhi High Court granted an ex-parte ad interim injunction in favor of Tata Sia Airlines Limited against Vistara Property Services Llp.

This immediate relief aims to prevent irreparable harm while the main suit proceeds.

The court directed domain registrars to block infringing domains, mandated banks to freeze suspicious accounts, and ordered telecom providers and government agencies (MeitY/DoT) to take steps to disable mobile numbers and block website access. This decisive order aims to protect the plaintiff's brand reputation and prevent further financial fraud.

The Delhi High Court allowed the petition filed by Abbott Products Operations Ag to cancel the trademark registration 'DUFAKWIK' (No. 4459400) in Class 05.

This order provides a clear example of how IP disputes can be resolved efficiently through negotiated settlements before the court.
