• Blood Centrifugation

    Sunstein prosecuted blood centrifugation patents for Haemonetics Corporation, a leader in the field of blood processing. The patented technologies allow blood components to be collected and processed for life-saving transfusions.

  • Purification

    Innovations by DEKA Research increase the efficiency of water purification systems, while reducing power and maintenance requirements. International patent applications like the one Sunstein prepared for DEKA can lead to worldwide adoption of a useful technology – one that can supply the developing world with access to safe water.

  • Shaft/hub

    Custom Machine & Tool Co. invented a novel shaft/hub connection device for precise component positioning and tight run-out control in demanding torque transmission applications such as timing-belt pulleys. Rigorous engineering analyses, as shown, demonstrate the benefits of CMT’s invention compared to other connection systems. The patent Sunstein obtained bolsters CMT’s position in a crowded marketplace.

  • Intravascular Stent

    Sunstein prosecuted a patent for a new stent that retains high radial strength but is more flexible and easier to insert into a patient’s coronary artery. The Crown™ stent is the product of our client DEKA’s collaboration with Cordis Corp., a Johnson & Johnson company, to improve the design of the Palmaz-Schatz® stent, the first intravascular stent proven to reduce blockage in arteries.

Winning at IPRs

Samsung Electronics Co., Ltd. v. Arendi S.A.R.L.

Samsung attacked our client’s patent in the Patent Trial and Appeal Board (PTAB) on grounds of obviousness. We persuaded the PTAB that an element of the claims was not disclosed by the cited references and thus prevented the inter partes review from even being instituted.

Motorola Mobility LLC, Google Inc., and Apple Inc. v. Arendi S.A.R.L.

Motorola, Google and Apple attacked the same patent as Samsung raising several additional grounds. Our arguments carried the day and the inter partes review was not instituted, freeing our client’s patent for unfettered assertion in court.

A.C. Dispensing Equipment Inc. v. Prince Castle LLC

We filed a petition for A.C. Dispensing requesting an inter partes review of a patent relating to a method for controlling the dispensing of specified volumes of liquid. The petition withstood Prince Castle’s preliminary response and the inter partes review has been instituted against all twelve claims of the patent.
