Laser Peening Patent Infringement Lawsuit Update

On May 11, 2011 MIC filed a second Request for Reexamination with the USPTO, again asking that the USPTO reexamine all of the claims of the ‘876 patent in light of various printed publications and affidavits submitted by MIC in the second Request. As expected, on January 17, 2012, the USPTO issued a Notice of Intent to Issue a Reexamination Certificate, wherein the USPTO once again stated its intent to confirm all 38 of the claims of the ‘876 patent in their originally issued form. As a result, all of the originally issued claims of the ‘876 patent remain valid and enforceable – LSP Technologies.

 


Patent Infringement Lawsuit Update

 

On June 8, 2010, LSPT filed a patent infringement lawsuit against Metal Improvement Company, LLC (“MIC”) in the U.S. District Court for the Southern District of Ohio, Eastern Division, alleging infringement of U.S. Patent No. 6,373,876 (the “‘876 patent”).  On September 3, 2010, MIC filed a Request for Reexamination with the U.S. Patent and Trademark Office (“USPTO”), asking that the USPTO reexamine the claims of the ‘876 patent in light of various printed publications submitted by MIC in the Request.  The Court stayed the lawsuit pending the outcome of the reexamination proceeding.  On March 25, 2011, the USPTO issued a Notice of Intent to Issue a Reexamination Certificate, wherein the USPTO stated its intent to confirm all 38 of the claims of the ‘876 patent.  On July 5, 2011, the USPTO issued a Reexamination Certificate, Ex Parte Reexamination Certificate No. US 6,373,876 C1, declaring:  “As a result of the reexamination, it has been determined that:  The patentability of claims 1-38 is confirmed.”  As a result, all of the claims of the ‘876 patent remain valid and enforceable.


3rd Int’l Conference on Laser Peening

Dr. Jeff Dulaney and Dr. Allen Clauer of LSP Technologies will attend the 3rd International Conference on Laser Peening & Related Phenomena on October 11-14, 2011 in Grand Cube Osaka, Japan.  Dr. Dulaney has joined the conference committee.

Dr. Dulaney will present on the topic Future Shock: Accelerating Technology, here is the abstract for his presentation.

It takes an enormous effort to take technology from a laboratory research environment to commercial use.  Laser Shock Processing (LSP) of the 1970s evolved into the commercial success known today as laser peening.  There are several variants of laser peening in use today, and others yet to be discovered, developed, and integrated into commercial use.  The study of the laser-generated shock waves, so critical to laser peening, will find commercial applicability beyond imparting compressive residual stress in metals.  Computer models, currently being used to support commercial applications development, will continue to improve and lead the way to new applications and uses.  Overlay materials will evolve to enhance the effectiveness of laser peening through the use of special materials and techniques.  In situ process controls and diagnostics will continue to be developed to provide real-time feedback for process control and continuous quality assurance as critical parts are being processed.  Advancement of laser peening systems will enable new and unexpected applications.

Dr. Clauer will present a paper he co-authored with Peter Gaydos entitled, “The Effect of Surface Treatments on Fatigue of Carburized X2M Steel.”   Here is the abstract for his paper.

“Carburized X2M specimens were tested in 3-point bending fatigue after having their surface treated with four different treatments both individually and in combination. The bend specimens were 102 mm x 34 x 8.5 mm, with the longitudinal edges of the tensile surface tapered. The surface treatments were Isotropic Surface Finishing (ISF), Low Stress Grinding (LSG), Shot Peening (SP) and Laser Shock Peening (LSP). The first three were also applied in combination with a follow-up LSP treatment, and also a combined ISF/SP/LSP treatment.
The results show that the fatigue strength increased with the type of surface treatment in the order of ISF, LSG, SP, LSP. The combination treatments produced fatigue strength equivalent to or slightly better than the LSP treatment alone.

These results will be discussed in the context of residual stress profiles and scanning electron microscopy of the surfaces and fracture surfaces. The observed modifications of the surfaces and comprehensive residual stresses lead to observable changes in crack initiation behavior.”

Other committee members from Ohio include:

Ramana V. Grandhi: Wright State University, USA

Kristina Langer: Wright-Patterson AFB, USA

S. R. Mannava: University of Cincinnati, USA

11th International Conference on Shot Peening

South Bend, Indiana

September 12-15, 2011
Booth #111

LSP Technologies happily returns to the the International Conference on Shot Peening in 2011.  David Lahrman and Steve Dykes will be attending the conference and will be available to discuss and explain the laser peening process.  Stop by and visit with them in our booth (#111).  We hope you will stop to learn more about laser peening and how it can improve the fatigue properties of the parts you manufacture or maintain.

The excerpt below from the 11th International Conference on Shot Peening website highlights shot peening alternative or supplemental processes.

“Related mechanical surface treatments, such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes including compressive surface residual stresses, are within the scope of the conference, especially when compared to shot peening.”  To read more, visit the conference website:

ICSP-11

11th International Conference on Shot Peening

LSP Technologies will be a presenter.

September 12-15, 2011
South Bend, Indiana

Scope
ICSP-11 will be the 11th International Conference on Shot Peening. Related mechanical surface treatments – such as deep rolling, laser peening, ultrasonic peening, combined processes and other cold work processes inducing compressive surface residual stresses – are within the scope of the conference, especially when compared to shot peening. Shot Peening and related mechanical surface treatments have proved to be powerful instruments in enhancing the resistance of components to various kinds of stress-induced damage, particularly with respect to fatigue and corrosion damage. The service lives of a wide variety of structural components, irrespective of shape and dimensions, can be improved dramatically by shot peening. The commercial benefits of applying mechanical surface treatments are increasingly recognized, especially in the automotive and aerospace industries.

LSP Technologies Licenses General Electric’s Laser Peening Patent Portfolio

LSP Technologies, Inc. is pleased to announce that it recently entered into a patent cross-license agreement with GE.  As a result of the cross-license, LSPT became the sole production-based licensee of GE’s entire laser peening patent portfolio, which includes more than 50 U.S. and foreign issued patents and numerous pending patent applications.  LSPT also became the sole production-based licensee of the coveted “GEN 4” laser peening technology, a relatively low power, high throughput laser peening technology that will revolutionize the laser peening industry.

LSPT’s laser peening customers can breathe easier knowing that LSPT is contractually permitted to process parts using GE’s extensive laser peening patent portfolio.  This exciting new development will allow LSPT to continue to be the premier provider of high quality, efficient, and value driven laser peening production services for many years to come.


Settlement of Continuum Litigation

LSP Technologies, Inc. is pleased to announce that it has settled both of its pending patent infringement lawsuits against Continuum Electro-Optics, Inc. The basis for the settlement was a license grant from LSPT to the purchaser and end user of the Continuum laser system covered by the patents at issue in the lawsuits (U.S. Patent Nos. 6,373,876, 6,191,385, and 5,127,019).

LSPT places a very high value on its patent portfolio, which includes roughly 60 U.S. and foreign patents and numerous pending patent applications relating to laser peening, laser bond inspection, and laser mine neutralization. LSPT will continue to seek enforcement of its patents where necessary and appropriate.
