Conqueror Innovations Private Limited & Anr. v.Xiaomi Technology India Private Limited
This appeal challenged the Single Judge's dismissal of the appellants' applications for interim injunction in a patent infringement suit. The appellants alleged that Xiaomi's smartphones, tablets, and other devices infringed their registered Indian Patent No. 244963 titled 'A Communication Device Finder System.' The Division Bench upheld the Single Judge's findings that the appellants failed to establish a prima facie case of infringement, as the respondent's 'Find Device' feature did not read onto the essential elements of the suit patent's independent claim. The court further held that the balance of convenience favored the respondent due to the appellants' unexplained nine-year delay in approaching the court, and accordingly dismissed the appeal.
