• 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.

Deep Patent & Trial Experience

Ariad Pharmaceuticals, Inc. v. Eli Lilly and Co.

We participated in the representation of Ariad, obtaining a $65 million jury verdict for infringement of our client’s patents for regulating NF-kappaB cell-signaling activity, the largest verdict in Massachusetts that year.

Comair Rotron v. Nippon Densan Corporation and Nidec Corporation

After securing a jury verdict of patent infringement, we negotiated a multimillion dollar settlement for our client Comair Rotron. The patent was directed to important magnetization technology for brushless DC electric motors.

In disputes over brand names, we have also delivered major successes to our clients.

Winning at IPRs

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.

Spotlight on Patents

diagram1 For our client Dr. Leslie Stern of Fall River, Massachusetts, we recently obtained US Patent No. 8,460,310, describing a medical device for use in minimally invasive spine surgery.

Our Latest Thinking

  • Trademark litigants might change their tactics now that the Supreme Court has held that rulings of the Trademark Trial and Appeals Board may preclude subsequent litigation of the same issue in federal court.

    More...
  • US patent owners can enforce their rights against infringers who act mostly overseas, but only to the extent of a nexus with the US.

    More...
  • For US inventors, it’s easy to get broader and stronger protection for industrial designs, now that the US has joined an international treaty.

    More...
  • Recent decisions put added pressure on software developers to recite a sufficiently definite structure to support means-plus-function patent claims.

    More...
  • The PTAB has typically construed patent claims more broadly than do the federal trial courts, which can expose patents to invalidation. The Federal Circuit has eased that concern by shrinking the difference between the administrative and judicial standards.

  • The Federal Circuit has brought order to the process of navigating patent challenges and appeals through the PTAB and federal courts.
