Court holds inventive step present in using spectrophotometer and invisible markers in end-to-end article management; rejects prior art mosaicing argument by Patent Controller
In a significant patent law ruling, the Madras High Court on 16th October 2026 allowed the appeal of The North Face Apparel Corp against the Controller of Patents and Designs, setting aside the refusal order dated 16th April 2025 and directing the grant of patent for the invention titled "Systems and Methods for End-to-End Article Management" (Indian Patent Application No. 202147026139).
The patent application was initially rejected on grounds of lack of inventive step and non-patentability. The Controller had relied on prior art documents D21 to D24 to hold that the claimed invention was obvious by dissecting the patent claims into isolated elements and comparing them with features in these prior art references. The Controller concluded that the invention lacked novelty and was a mere mosaic of existing teachings.
However, the Madras High Court disagreed with this approach, emphasizing that the examiner impermissibly dissected the claims and failed to consider the invention as a whole. The Court noted that the cited prior art documents had materially different objectives and teachings compared to the appellant's invention. Specifically, the invention integrates invisible markers and a spectrophotometer-based system to dynamically detect and correct discrepancies during the manufacturing of apparel and related articles-features not disclosed or suggested in the prior art.
The Court observed that the prior art D21 involved automated production of personalized garments using scanners but did not address error detection or correction; D22 used optically readable codes but not invisible markers; D23 described centralized control networks but not the bidirectional data flow architecture claimed; and D24 involved carrying process information across manufacturing stages but did not involve the technical advances of the appellant's system.
Rejecting the Patent Controller's "mosaicing" or hindsight reconstruction argument, the Court held that the invention involved a technical advance with industrial applicability. The use of invisible markers detected via spectrophotometer for continuous monitoring and process rectification was a novel feature that enhanced manufacturing precision and efficiency.
The judgment underscores that patent examiners must evaluate inventive step by considering the invention in its entirety rather than isolating claim elements. It also affirms that combining teachings from unrelated prior art with different objectives cannot negate inventive step without clear motivation.
Accordingly, the Madras High Court set aside the refusal order and directed the Controller to grant the patent, marking a victory for The North Face Apparel Corp and setting important precedent on inventive step analysis in patent prosecution.
Bottom Line:
Patents - Refusal of patent on ground of lack of inventive step - Examiner cannot dissect claims into isolated elements and reject application by mosaicing prior art documents having different objectives - Use of spectrophotometer to identify invisible markers in end-to-end article management process held to involve inventive step and industrial application - Refusal order set aside and patent directed to be granted.
