- AGA Medical
- Arctic Cat
- Buffalo Wild Wings
- Hormel Foods
Represent the world’s leading medical products provider in various patent and licensing disputes. In one case, we filed suit against a competitor in the Middle District of Florida. Our team obtained a consent injunction, forcing the opponent to stop selling the infringing product at an early stage, before the claim construction hearing.
Currently defend a manufacturer of wireless intercom systems in a patent infringement lawsuit filed by 3M. We obtained a stay of the case pending reexamination of the patents. We have been adverse to 3M nine times in the last five years.
Successfully defended accused patent infringers in the Eastern District of Texas. Our clients faced an opponent seeking $64 million in damages. The case was quickly settled after the jury returned an award of $3 million, well below any prior settlement demand.
Defended AGA Medical in a licensing dispute initially valued by the plaintiff at $300 million, including a two-phased trial in the spring of 2013. After trial, and raising a concern over the validity of the license agreement, the presiding judge initiated a settlement conference that lead to a favorable settlement well below pretrial settlement demands.
Represented a mortarless retaining wall design company in a trial and two appeals regarding the company’s enforcement of a license agreement in the Western District of Wisconsin and the Seventh Circuit Court of Appeals, resulting in a finding of liability, injunction and full damages award.
Represented Medtronic in licensing disputes with various parties. In one instance, we were able to convince a licensee, without resorting to litigation, to restart and complete license payments after it initially determined it could cease payments, resulting in $2 million in additional royalties.
Defend trademarks owned by a Minnesota manufacturer of off-road vehicles in trademark litigation. In 2012, we obtained a favorable global settlement in a trademark dispute involving our client’s primary logo. We are currently defending the client in a trademark infringement case involving one of the client’s best-selling products.
Represented a well-known restaurant chain in trademark and trade dress enforcement proceedings. In 2012, we obtained a permanent injunction against a competing restaurant chain requiring the competitor to change the restaurant’s logos and color scheme.
Represent the world’s leading medical device provider in trademark enforcement and TTAB proceedings. In one recent case, the defendant changed the infringing advertising materials in response to our preliminary injunction motion.
Trade Secret Litigation
Represented a medical device company in a lawsuit to protect its trade secrets. Our client developed a new technology and entered into a non-disclosure agreement with a potential vendor. The vendor later applied for a patent that incorporated our client’s technology. We filed suit and achieved a settlement that keeps the competitor out of our client’s market.
- Represented a manufacturer of electronic medical records software in trade secret litigation with the former employee of a development partner. Our client co-developed key software that performs natural language processing of medical records. One of the principal designers of the software subsequently left our client’s development partner, taking copies of the software’s source code with him and deleting the code from his employer’s computers. When our client learned that the former employee was attempting to sell the software to other customers, we joined in a lawsuit with our client’s co-developer to protect the technology and recover the stolen source code. The case was tried before a jury in federal court for the U.S. District of Minnesota, and the Court ruled in favor of our client on all claims.

Parties facing allegations of willful patent infringement can rebut the claim by proving that they relied in good faith upon the advice of counsel when undertaking the allegedly infringing activity. However, asserting the advice of counsel defense carries a heavy cost - waiver of privilege as to at least the attorney work product and attorney-client communications relied upon in formulating the opinion. Some courts have even extended the scope of this waiver more broadly to cover any information even considered by the advising counsel. This tradeoff leads many to forego raising the advice of counsel defense.Read More

Under 28 U.S.C. § 1404(a), “[f]or the convenience of parties and witnesses, in the interest of justice, a district court may transfer any civil action to any other district or division where it might have been brought.” When a party moves to transfer venue under § 1404(a), courts consider: (1) “the convenience of the parties,” (2) “the convenience of the witnesses,” (3) “the interests of justice,” and (4) “any other relevant factors when comparing alternative venues.” A recent opinion from Judge Nelson in the The Valspar Corporation and Valspar Sourcing, Inc. v. PPG Industries, Inc. case provides useful guidance for parties considering such a motion, especially concerning the convenience-of-the-parties prong of the analysis.Read More

Magistrate Judge Hildy Bowbeer Offers Further Guidance on When a Court Should Order a Patentee to Reduce the Number of Asserted Claims
March 1, 2016
A Patent holder bringing an infringement suit sometimes brings suit to enforce hundreds of patent claims and may have little motivation to drop asserted claims until late in the litigation, leaving a defendant and the Court with numerous claims in the pre-trial phase. A recent case before Magistrate Judge Bowbeer offered further guidance on how and when courts should reduce the number of asserted claims.Read More

It is not uncommon for a party seeking to license or acquire a patent to request information from the patent holder regarding the patent’s validity and strength. Often, this includes highly confidential documents between the patent holder and attorneys, which are generally privileged and protected from disclosure. However, disclosing privileged documents to a third party usually constitutes a waiver of the privilege. In limited circumstances, the “common interest doctrine” allows two or more entities with a joint interest to share privileged information without waiving its protection. This can include, for example, communications between separate parties negotiating a patent license. Before disclosing any privileged communications to a potential licensee, though, a patent holder should carefully consider whether they may be discoverable in subsequent litigation by a party seeking to invalidate the patent.Read More

In a lawsuit that redefined the standard for an exceptional case under 35 U.S.C. § 285, the District Court awarded defendant Octane Fitness $1,778,030 in fees and costs. The District Court initially denied Octane Fitness’ motion for fees. But after the Supreme Court redefined the standard on appeal, reversed and remanded the case (Octane Fitness, LLC v. Icon Health & Fitness, Inc., 134 S. Ct. 1749 (2014)), the District Court found the case exceptional under the new standard.Read More

In 1964, the Supreme Court decided Brulotte v. Thys and held that a patent owner cannot charge royalties for the use of a patented invention after the patent’s term has expired.

Lower courts and academics alike have challenged the economic logic underlying the rule and criticized the decision as counterintuitive.Read More

Despite the Supreme Court’s recent Commil USA, LLC v. Cisco Systems, Inc. decision, invalidity opinions of counsel remain an important tool for mitigating patent infringement risk. Under Commil, invalidity opinions cannot be used to show that an accused infringer lacked the requisite intent to induce—i.e., the scienter element—under 35 USC § 271(b). But companies will continue to use the opinions to memorialize early-stage validity analyses as part of a broader strategy of assessing potential patent infringement risk.Read More
