Can a Sensor-Based Technical be a Mental Act under Section 3(m)?

Can a Sensor-Based Technical be a Mental Act under Section 3(m)?


The recent decision in Bosch v. The Deputy Controller of Patents prompted a closer lookโ€”not just for its resolution under Sec. 3(m), but also for the thought it raises: could the invention have been treated differently if it had been classified by IPO under another domain?

Sec 3(m) of the Indian Patents Act excludes from patentability โ€œa mere scheme or rule or method of performing a mental act or method of playing a game.โ€

The present invention, however, claimed a method for:
– Measuring fuel and ambient temperatures using sensors
– Calculating and applying heating power to a fuel heater
– Controlling the temperature of the injected fuel
– Enabling engine startup based on fuel temperature reaching a predefined threshold

Although involving an ‘๐—ฎ๐—น๐—ด๐—ผ๐—ฟ๐—ถ๐˜๐—ต๐—บ๐—ถ๐—ฐ’ ๐˜๐—ฒ๐—ฐ๐—ต๐—ป๐—ถ๐—ฐ๐—ฎ๐—น sequence and having ๐—ต๐—ฎ๐—ฟ๐—ฑ๐˜„๐—ฎ๐—ฟ๐—ฒ components, this case was classified under the ‘๐—–๐—ต๐—ฒ๐—บ๐—ถ๐—ฐ๐—ฎ๐—น’ ๐—ณ๐—ถ๐—ฒ๐—น๐—ฑ of invention and was treated accordingly and ultimately refused under Section3m and other grounds.

๐—ช๐—ต๐˜† ๐˜„๐—ฎ๐˜€ ๐—ถ๐˜ ๐—ฟ๐—ฒ๐—ณ๐˜‚๐˜€๐—ฒ๐—ฑ under 3(m)? The method was viewed as ‘๐˜๐—ต๐—ฒ๐—ผ๐—ฟ๐—ฒ๐˜๐—ถ๐—ฐ๐—ฎ๐—น’ and ‘๐—ป๐—ผ๐˜ ๐—ฟ๐—ฒ๐˜€๐˜‚๐—น๐˜๐—ถ๐—ป๐—ด ๐—ถ๐—ป ๐—ฎ ๐—ฝ๐—ฟ๐—ผ๐—ฑ๐˜‚๐—ฐ๐˜.’

The applicant appealed. The Madras High Court ๐—ฑ๐—ถ๐˜€๐—ฎ๐—ด๐—ฟ๐—ฒ๐—ฒ๐—ฑ with the refusal and set aside the rejection.

It held: โ€œThe method claim is in respect of a claimed inventive ๐—ฝ๐—ฟ๐—ผ๐—ฐ๐—ฒ๐˜€๐˜€ ๐—ฐ๐—ผ๐—บ๐—ฝ๐—ฟ๐—ถ๐˜€๐—ถ๐—ป๐—ด ๐—ฎ ๐˜€๐—ฒ๐—ฟ๐—ถ๐—ฒ๐˜€ ๐—ผ๐—ฟ ๐˜€๐—ฒ๐—พ๐˜‚๐—ฒ๐—ป๐—ฐ๐—ฒ ๐—ผ๐—ณ ๐˜€๐˜๐—ฒ๐—ฝ๐˜€, and cannot be characterized as a mere method of performing a mental act. Therefore, it clearly does not fall within the scope of Section 3(m) of the Patents Act.โ€

The Court sent the matter for fresh examination, specifically excluding any objection under 3(m).

The ๐—ฐ๐—น๐—ฎ๐—ฟ๐—ถ๐˜๐˜† this case brings is subtle but significant: ๐— ๐—ฒ๐˜๐—ต๐—ผ๐—ฑ๐˜€ ๐—ถ๐—ป๐˜ƒ๐—ผ๐—น๐˜ƒ๐—ถ๐—ป๐—ด ๐—ฎ ๐˜€๐˜๐—ฟ๐˜‚๐—ฐ๐˜๐˜‚๐—ฟ๐—ฒ๐—ฑ ๐—บ๐—ฒ๐˜๐—ต๐—ผ๐—ฑโ€”๐—ฒ๐˜ƒ๐—ฒ๐—ป ๐—ถ๐—ณ ๐˜๐—ต๐—ฒ๐˜† ๐—ฑ๐—ผ ๐—ป๐—ผ๐˜ ๐—ฐ๐˜‚๐—น๐—บ๐—ถ๐—ป๐—ฎ๐˜๐—ฒ ๐—ถ๐—ป ๐—ฎ ๐—ฝ๐—ต๐˜†๐˜€๐—ถ๐—ฐ๐—ฎ๐—น ๐—ฝ๐—ฟ๐—ผ๐—ฑ๐˜‚๐—ฐ๐˜โ€”๐—ฎ๐—ฟ๐—ฒ ๐—ป๐—ผ๐˜ ๐—ฒ๐˜…๐—ฐ๐—น๐˜‚๐—ฑ๐—ฒ๐—ฑ ๐˜‚๐—ป๐—ฑ๐—ฒ๐—ฟ ๐Ÿฏ(๐—บ).

But the case also prompts a broader reflection around its refusal by the IPO: ๐—ช๐—ต๐—ฎ๐˜ ๐—ถ๐—ณ this invention had been initially classified under domain โ€˜๐—˜๐—น๐—ฒ๐—ฐ๐˜๐—ฟ๐—ผ๐—ป๐—ถ๐—ฐ๐˜€โ€™ or โ€˜๐—–๐—ผ๐—บ๐—ฝ๐˜‚๐˜๐—ฒ๐—ฟ ๐—ฆ๐—ฐ๐—ถ๐—ฒ๐—ป๐—ฐ๐—ฒโ€™?

In such areasโ€”including embedded control, signal processing, AI and other software related inventions โ€”method claims often do not produce a physical product, yet are treated as patentable because they achieve technical outcomes through repeatable, measurable steps.

Could this method, then, have been treated differently had the application been classified and treated through those domains instead?

If so, perhaps the ๐—ฏ๐—ฟ๐—ผ๐—ฎ๐—ฑ๐—ฒ๐—ฟ ๐˜๐—ฎ๐—ธ๐—ฒ๐—ฎ๐˜„๐—ฎ๐˜† is not just that method claims are patentable even if they do not “produce a product”โ€”but also that an inventionโ€™s initial classification at the IPO might shape its outcome too.
