Achieving Favorable Results in Courts Across the Country

Philips/Signify has asserted patents in its EnabLED Licensing Program in U.S. Courts and at the ITC numerous times.  Radulescu LLP has been involved in many of these litigations, including:


Koninklijke Philips N.V. and Philips Lighting N. Am. Corp. v. Wangs Alliance Corp. d/b/a WAC Lighting Co., 14-cv-12298-DJC (D. Mass.).  The following U.S. patents were asserted by Philips Lighting: 6,013,988; 6,147,458; 6,250,774; 6,561,690; 6,586,890; 6,788,011; 7,038,399; 7,256,554, 7,352,138 and 7,737,643.  Engaged by WAC Lighting to replace defense counsel a year into the case and after claim construction briefing was completed.  Achieved successful resolution after important strategic wins, including: achieved institution of IPRs on 6 out of 7 Petitions for invalidity filed before the USPTO; prevailed on a related motion to stay the District Court proceedings pending IPRs; succeeded on preventing damages discovery before case was settled; prevailed on a rare decision limiting the scope of IPR estoppel of invalidity to only those grounds raised in WAC Lighting’s Petitions, thus allowing WAC to maintain most of its prior art invalidity defenses for trial and increasing pressure on Philips.


Philips Lighting Holding B.V. v. Howard Indus., Inc. d/b/a Howard Lighting, 2:18-cv-12-KS-MTP (S.D. Miss.).  Philips asserted the following five U.S. patents: 6,250,774; 6,577,512; 6,586,890; 7,262,559; and 8,063,577.  Represented Howard Lighting.  Achieved successful resolution via important strategic considerations.  Along with an answer to the Complaint, we filed a motion for judgment on the pleadings in connection with the ‘774 patent (where we argued no pre-suit damages).  We prevailed on that motion, which forced Philips’ patent claims to be limited to LED drivers and not the overall LED lighting products.  This positioned Howard to be able to argue, based on the compelling weight of the law, that any royalty base must be tied only to the cost of the LED drivers and not the overall products, substantially reducing the exposure of our client.


In re Certain LED Lighting Devices, LED Power Supplies, and Components Thereof, 337-TA-1081 (ITC). Philips asserted the following three patents against client WAC Lighting in an ITC investigation against seven respondents: 6,586,890; 7,038,399; 7,256,554.   Achieved successful resolution after several important strategic wins.  Philips attempted to assert an additional patent against WAC Lighting, a motion which we defeated based on the prevailing law (which Philips ignored).  We also obtained several favorable claim constructions and presented strong invalidity positions leading to Philips’ withdrawal of certain claims and the ‘890 patent—which had been asserted in many cases by Philips—in its entirety.


Winning at the PTAB to Invalidate Philips’ Patent Claims

We successfully invalidated claims at the PTAB from several of Philips’ patents, including U.S. Patent Nos. 6,013,988, and 6,586,890.

Winning at the Federal Circuit

Finding itself on the receiving end of our successful PTAB results, Philips appealed the invalidation of claims in U.S. Patent Nos. 6,013,988 (“the ‘988 patent”) and 6,561,690 (“the ‘690 patent”) to the appellate court for all patent matters, the Court of Appeals for the Federal Circuit. Once again, we successfully argued against Philips, with the Federal Circuit completely affirming the PTAB’s decisions that claims of the ‘988 patent and ‘690 patent were unpatentable.


Deep Knowledge of Philips’ Patents Across Market Segments

Over the last several years, we have substantial and unmatched expertise with hundreds of Philips LED patents.  Our experience spans the gamut of LED patents in the following market segments: LED bulbs, electronic/driver circuitry, outdoor luminaires, parking and street lights, indoor lights, industrial lighting, and horticultural lighting.  We have also unmatched experience in virtually every single Philips patent asserted in litigation over the years, including the following U.S. patents:


6,013,988               6,586,890               7,352,138

6,147,458               6,788,011               7,358,679

6,250,774               7,038,399               7,737,643

6,561,690               7,178,941               8,063,577

6,577,512               7,256,554               8,070,328
