Daniel I. Konieczny

Daniel Konieczny represents a diverse group of clients from Fortune 500 businesses to individuals in lawsuits involving complex issues in intellectual property, state and local tax, insurance coverage, trusts and estates, employment agreements, professional liability, and other areas.  He is a patent attorney licensed to practice before the U.S. Patent and Trademark Office (“USPTO”).  He has successfully represented clients at trial and on appeal in state and federal court, in arbitrations and mediations, and before the Patent Trial and Appeal Board of the USPTO. 

Mr. Konieczny graduated from Harvard Law School in 2001, and he graduated magna cum laude from Princeton University in 1998, where he majored in physics and earned certificates in applied mathematics and public policy. 

Mr. Konieczny’s professional accomplishments include:

  • Representing the owner of a patent covering motion tracking systems with applications in helmet mounted displays in an inter partes review proceeding before the Patent Trial and Appeal Board of the USPTO, in two separate appeals before the Federal Circuit, and in the Court of Federal Claims.
  • Representing the Regional Transportation Authority before the Illinois Supreme Court in litigation over the appropriate legal test to determine how Illinois sales tax should be assessed.  The Illinois Supreme Court unanimously agreed with our client’s contentions as to how such taxes should be assessed, while ruling that certain regulations promulgated by the Illinois Department of Revenue were invalid.
  • Protecting the trade secrets and confidential information of a manufacturer of innovative food packaging materials in a dispute against a Fortune 100 company.  The claims were settled to our client’s satisfaction within six months after we filed the complaint.
  • Obtaining dismissal of an Illinois False Claims Act complaint as a matter of law, which alleged that our client failed to collect and remit use tax on shipping and handling charges on Internet sales.
  • Obtaining a favorable judgment at trial for another retailer sued under the Illinois False Claims Act based on allegations that the retailer failed to collect and remit use tax on Internet sales.
  • Representing a Fortune 500 company in a pending lawsuit against numerous insurers involving over $1 billion in potential coverage for asbestos liability.
  • Obtaining judgment in favor of a trustee of several interrelated family trusts following trial on all remaining claims for breach of fiduciary duty, after obtaining dismissal of several other such claims as a matter of law.  The judgment fully exonerated the trustee and confirmed the trustee’s continuing authority to make trust decisions.
  • Successfully defending against patent infringement claims based on the on-sale bar and other defenses.
  • Successfully representing a large, privately held media distributor in trademark, unfair competition, copyright infringement and copyright misuse litigation against a major competitor.
  • Obtaining a temporary restraining order against our client’s former employee, who sought to compete in violation of his employment agreement with our client.

In 2014, Mr. Konieczny conducted a roundtable discussion addressing topics in excess insurance disputes at the American Bar Association's Insurance Coverage Litigation Committee CLE Seminar, in Tucson, AZ. 

In conjunction with his partner Gino DiVito, Mr. Konieczny maintains a guide to the Illinois Rules of Evidence, which is available on the firm’s website and as a publication of the Illinois State Bar Association.  The 200+ page guide includes a detailed comparison of the Illinois and Federal Rules of Evidence and extensive commentary on the Illinois and Federal Rules.

Since 2011, Mr. Konieczny has been named an Illinois “Rising Star” by his peers in SuperLawyers® Magazine, a distinction reserved for the top 2.5% of Illinois lawyers who are under 40 or in practice for 10 years or less.

He is a member of the Illinois bar, the trial bar of the U.S. District Court for the Northern District of Illinois, and the bars of the Federal Circuit and the Seventh Circuit, and he has represented clients in lawsuits in state and federal courts across the United States.
