placed significant reliance
on expert testimony of two kinds - first, on X-ray diffraction tests which

specification of the aforementioned patent or the x-ray diffraction of the
product (tablet) Tarceva or the defendant‟s Erlocip was indicated ... purchased some manufactured in August 2006 from the local
market. The x-ray diffraction data of Tarceva sold in India showed that

crystalline form has its own X-ray diffraction pattern.
This X-ray diffraction pattern is inherent property of
each ... which would lead to the claimed
invention.
(iv) The x-ray diffraction pattern is an
inherent property of each crystalline
compound, and the crystalline
