This judgment settles several critical points in patent litigation, particularly for biologics in quia timet scenarios, affirming that product-to-claim mapping under Rule 3(A)(ix) of the Delhi High Court Patent Suits Rules cannot be entirely dispensed with, even in anticipatory actions; the phrase “to the extent possible” allows flexibility but demands maximum feasible effort, and collateral evidence alone may not suffice for prima facie infringement without raising triable issues.

This judgment settles that in trademark disputes involving registered marks, no statutory infringement action lies against another registered proprietor under Section 28(3) of the Trade Marks Act, 1999, but passing off remains actionable under common law via Section 27(2), provided the plaintiff proves prior goodwill predating the defendant’s use, misrepresentation, and damage.

The Division Bench’s reasoning pivoted on a critical procedural distinction between interim relief and final rectification under Section 57 of the Act. While acknowledging the Single Judge’s analysis of phonetic similarity—observing that “INSEAD” and “INSAID” shared auditory traits that could invoke initial interest confusion, especially in educational services—the court noted that these conclusions were repeatedly qualified as “prima facie.” For instance, the Single Judge held that phonetic similarity existed based on examples like “dead” and “said,” and that even enlightened students might experience momentary wonderment upon encountering the marks, satisfying the likelihood of confusion test under Section 11.

This case revolves around a rectification petition under Section 57 of the Trade Marks Act, 1999, where the petitioner sought the cancellation or removal of the respondent’s trademark ‘GMW’ in Class 11, arguing it was deceptively similar to their own ‘GM’ marks used since 1999 in the electrical goods sector. The court, presiding over an ex-parte proceeding due to the respondent’s non-appearance, emphasized the overriding principle that prior adoption and continuous use, backed by substantial goodwill evidenced through sales and registrations, prevail over later registrations that could lead to confusion or passing off.

The court ruled in favor of the petitioner, emphasizing how extensive historical usage and acquired reputation can trump subsequent registrations that appear to capitalize on established goodwill. This decision not only reinforces the protective mechanisms of the Trade Marks Act but also highlights the judiciary’s role in maintaining the purity of the trademark register by eliminating marks that could lead to consumer confusion and unfair trade practices. At its core, the case illustrates the delicate balance between innovation in branding and the safeguarding of legacy marks in competitive markets like pharmaceuticals and ayurvedic products, where phonetic and structural similarities can easily mislead the average consumer.
