Callie J. Sand

Specialty / focus. Callie J. Sand is an IP litigation shareholder in Greenberg Traurig's Chicago office, concentrating on patent, trademark, and trade secret litigation. Her technology docket spans consumer electronics, cellular/wireless communications, semiconductors, medical devices, consumer goods, and software, and she has handled matters in district court, the U.S. Patent and Trademark Office, and the ITC. She is a registered patent attorney (USPTO Reg. No. 73254) with a physics background.

Side preference. Sand's tracked appearance is defendant-side (1 defendant representation, 0 plaintiff), and her broader Law360 docket (30 matters) is consistently defense-oriented: she represents operating-company defendants such as Lenovo, American Airlines, and Carters in Texas Eastern patent suits brought by NPEs/PAEs (e.g., WeCrevention Inc. v. Lenovo Group Limited, Secure Matrix LLC v. American Airlines, Inc., ORIBEL PTE LTD v. Carters Inc.). Her firm bio does include some enforcement work (e.g., sporting goods helmet patents), but the weight of her practice is defending manufacturers and operating companies.

Firm context. Sand is a shareholder at Greenberg Traurig, elevated to that position in February 2024 after joining the firm's Intellectual Property & Technology practice; available sources do not identify any prior law firm, so her pre-Greenberg career history is unverified. She has been recognized in Best Lawyers "Ones to Watch" (2021–2024) and Leading Lawyers "Emerging Lawyers" (2024–2025).

Notable outcomes & PTAB. Firm-reported results include summary judgment of no willful infringement and noninfringement based on patent exhaustion in a wireless-communications case, an ITC early termination after an ALJ found the asserted patent indefinite, and an ED Texas claim-construction order finding all asserted claims indefinite. These are firm-bio self-reports and not independently verified here. IPR and other post-grant proceedings are a listed concentration, and she is admitted to practice before the PTAB, but no specific IPR/PGR proceedings were verified in this search.

Bar / education. Admitted in Illinois and California, plus the Seventh Circuit, Federal Circuit, and USPTO; J.D., cum laude, University of Michigan Law School (2013); B.A. in Physics, magna cum laude, Carleton College (2010).
