The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "A photography optical lens assembly includes four lens elements (E1, 5 E2, E3 and E4) which are, in order from an object side to an image side: a first lens element (E1), a second lens element (E2), a third lens element (E3) and a fourth lens element (E4). Each of the four lens elements (E1, E2, E3 and E4) has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The first lens element (E1) has positive 10 refractive power. The third lens element (E3) has positive refractive power, the object-side surface of the third lens element (E3) is concave in a paraxial region thereof, and the image-side surface of the third lens element (E3) is convex in a paraxial region thereof. The object-side surface and the image-side surface of the third lens element (E3) are both aspheric. At least one of the object-side 15 20 surface and the image-side surface of the third lens element (E3) has at least one inflection point (P)."
