“As a witness in the $273M trial, Altavion, Inc. vs. Konica Minolta Systems Laboratory, Inc. et al (Case Number CIV 467662), I have now known John Costello for many years. He is a critical thinker, master of patent law, superlative strategist, excellent lawyer and an outstanding individual. John Costello is superb in his ability to assemble a legal team to meet the myriad challenges faced in an intellectual property lawsuit, especially when the legal defense is an internationally recognized law firm.

I highly recommend John for any patent counseling, litigation strategy, and any patent litigation matters. No lawyer can win every case or every motion (despite what you may hear), but John will put you in the best possible strategic position and give you the highest probability of winning.”

“I wholeheartedly recommend John Costello not only for his general legal and IP expertise and acumen, but also for his character, honesty and strong, work ethic. I had the pleasure of working for and learning from John as a law clerk, and this experience and his influence as a mentor and example has had a profound, positive influence throughout my legal career from law school student to associate to legal head of a publicly-traded corporation to now, partner of a large, national firm. Without hesitation, I have recommended John and his legal services to others in the past and will continue to do so in the future.”

reported to John at Costello Law Corporation

“”In mid 2007 I approached Mr. Costello on behalf of my company Altavion, Inc. with a very complex civil case against Konica-Minolta for their massive theft of very rare intellectual properties which they filed into 42 patents applications. Defendant has been granted 11 US Patents they never invented. John identified the needs and assembled a team of other attorneys with him. This included Mr. Glenn Peterson the master litigator and Pamela Bertani. John showed me a very rare caliber of professionalism in navigating the course of the case and bringing the necessary top notch experts in various fields to look at the case and testify on our behalf. He managed the case very well and brought in two top notch experts who articulated the damages and navigated through the patent law. Apparently the case became more complex with the Defendant filing for more patents even during the course of the lawsuit. Yet, John and the team together showed me a level of patience and controls which were beyond my expectations. John was always there taking charge of details and cooperating with an excellent team of equal caliber of attorneys of different skills. We all worked as a family facing an army of nearly 12 defense attorneys. Yet, they were no match to the skilled team assembled by John.

I strongly commend and recommend him and his team for tough tasks which I witnessed.

hired John as a Attorney in 2007

“I regularly rely on John’s patent expertise. I highly recommend his services. John’s opinions have withstood the test of both time and litigation. John’s patent prosecution background is now complemented by his litigation experience. He logged more hours in a courtroom in 2010 than 90% of the full time litigators I know. This perspective makes him unique among his peers in the patent bar and is an invaluable complement to his prosecution experience.”

hired John as a Attorney in 2000, and hired John more than once

“I had the pleasant opportunity to work with John when I was the technical expert for Altavion in the Altavion case against Konica-Minolta in 2009-2011. John is an excellent person with sharp mind and pleasant personality for a lawyer 🙂 You really cannot escape making friends with this guy who has high ethics and beliefs even though his work has to do with lawsuits. I recommend John for any corporate lawsuits that imply patent infringements and trade secret violations. He is a very professional person with excellent staff and they do pay you on time.”
