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.

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.

LSP Technologies offers affordable laser peening services to improve the fatigue properties of our customer’s military, aerospace, power generation, tube forming, or other types of parts.  We collaborate with our customers to enhance their products with this innovative laser technology by increasing reliability, improving safety, and adding value.  We also provide an innovative non-destructive method of inspecting glue bonds in metals and/or composties that can detect “kissing bonds”.

Mr. David Lahrman will present a paper he co-authored entitled, “The LaserPeen™ Process and Emerging Applications”  September 12-15, 2011 at the 11th International Conference on Shot Peening.
ABSTRACT

“Laser peening has been demonstrated as a unique and valuable method to increase the resistance of aircraft gas turbine engine compressor and fan blades to foreign object damage (FOD) and improve high cycle fatigue (HCF) life.  Laser peening is also known as the LaserPeen^™ Process or laser shock processing (LSP).

 Laser peening drives a high amplitude shock wave into a material surface using a high-energy laser pulse.  The plastic deformation caused by the shock wave results in deep compressive residual stresses in the surface of the part.  The depth and magnitude of the residual stresses depend upon the material and the processing parameters.  Compressive residual stresses typically extend as deep as 0.040-0.060 inches (1.0 to 1.5 mm) below the surface and can approach the yield strength of the material.  These compressive residual stresses increase the resistance of materials to surface-related failures such as fatigue, fretting fatigue, and stress corrosion cracking.

 The successful use of laser peening on aircraft turbine engines blades is driving development efforts to expand the use of this technology to airframe structures, automotive gears, medical devices, nuclear systems, and general industrial applications.  The laser peening process is described and factors important for successful applications are discussed.”

Two additional papers are planned to be presented.  One by Yunfeng Cao and Yung C. Shin of the Center for Laser-based Manufacturing at Purdue University entitled, “Predictive self-closed modeling of laser shock peening and parametric study,” another by Anoop Vasu1 and Ramana V. Grandhi2 of the Department of Mechanical and Materials Engineering at Wright State University entitled, “Compressive Residual Stress Optimization in Laser Peening of a Curved Geometry.”  Follow the links below to read the abstracts for these two papers.

Compressive Residual Stress Optimization in Laser Peening of

Laser peening also known as laser-peening or laser shock processing (LSP) increases the resistance of materials to surface-related failures such as, FOD, fatigue, fretting fatigue, and stress corrosion cracking.  It does this by driving compressive residual stresses into metals and alloys. 

Please stop by our booth, David Lahrman will be available for discussion about the benefits that laser peening surface enhancement technology can provide your parts to reduce their fatigue susceptibility.  See the beneifts of laser peening on our FAQs page at http://lsptechnologies.com/questions/.

David Lahrman will also be available to discuss Laser Bond Inspection.  It is LSP Technologies’ new NDE method to inspect adhesive bond joints in composites or other bonded materials.  LBI uses a localized stress wave created by a laser beam of high peak power with a short pulse to create an internal disbond in weak bonds that is detectable by the laser bond inspection system itself or by a post test ultrasonic inspection.

LSP Technologies, Inc. will be exhibiting at DMC 2011. We hope you will visit us at booth number 628.

November 28 – December 1, 2011
Anaheim, California
Anaheim Convention Center
Booth Number: 628

The DMC is the flagship defense manufacturing technology forum for exchanging ideas, assessing technical project progress and dealing with the challenges of the many new and traditional defense industrial base issues across the services and agencies.

LSP Technolgies is pioneering the field of using high energy lasers to non-destructively inspect adhesive bonds in composite and other bonded materials for weak or “kissing” bonds.

The use of controlled, localized stress waves in materials and bonded joints offers new opportunities for the characterization of structures.  Bonded joints in particular benefit from this application because there is no nondestructive inspection method to measure bond strength.  LSP Technologies’ Laser Bond Inspection uses a high peak power short pulse laser to perform a localized proof test of a bond. The method can be nondestructively applied to strong bonds but will fail a weak bond, creating an internal disbond that is detectable by the laser bond inspection system itself or by post test ultrasonic inspection. 

To date numerous tests have shown the method to be sensitive to weak bonds in carbon fiber reinforced polymer composites structure bonds created by poor adhesive mixing, improper surface preparation or contamination.
