The ‘704 patent is owned by Carl Zeiss X-Ray Microscopy, Inc. (“Zeiss”) and generally claims X-ray imaging systems that incorporate projection magnification. Projection magnification utilizes diverging X-rays that spread out as they travel from a source. Due to this divergence, the distance between the X-rays emanating from the source continues to increase after interacting with the sample being imaged and prior to being received by a detector. As a result, the generated image is larger than the sample itself.

Sigray, Inc. (“Sigray”) filed a petition for IPR of the ‘704 patent, challenging all claims as anticipated or rendered obvious by a scientific paper (“Jorgenson”) describing an x-ray imaging system. Jorgenson attempts to reduce concerns related to projection magnification by providi
