The Six Filament Lamp Related Patents, You Know

- Sep 08, 2016 -

Crystal wafer photoelectric (electric) in the United States time 2016/8/30 northern California in the United States district court for Adamax (in Newhouse Lighting brand sales) filed a patent infringement lawsuit.


Crystal electricity in the lawsuit, said Newhouse infringement of six patents of crystal electric Lighting products, and apply for a court to issue injunction to prohibit Adamax continue to sell infringing the New house of Lighting products.


Crystal electricity in the lawsuit, it is pointed out that the New house Lighting filament bulbs, for example, adjustable light the candle 3.5 watts LED retro-styled Edison filament lamp, crystal electricity in the United States patent infringement, including: US6346771, US7489068, US7560738, US8240881, US8791467, US9065022.

Here introduced the six patents:



1 us6346771



The patents on November 19, 1998 by the Swiss UnisplayS. A. company to apply for, and on February 12, 2002 invention patents authorization. On December 2, 2011 patents transferred to electricity.

The patent of the principal right requirements:



LED chips, transparent, with the semiconductor substrate, N electrode with branching electrode chip.


This patent is abstractly summarizes, the characteristics of the sapphire substrate LED chip.


The patent application in 1998, is almost the predictive to describe more than 10 years after the market mainstream LED chip (sapphire substrate LED technical characteristics.


Crystal electric buy the patent, for the sapphire substrate LED chip patent lawsuits, considerable damage.


2 us7489068



The patents on January 6, 2006 by the crystal power application, and on February 10, 2009 invention patents authorized.


The patent of the principal right requirements:



Graphical transparent substrate LED chip.


Full use of the patent document writing skills, to expand protection range from the chip transparent substrate to chip + transparent substrate, directly to a wire filament encased "transparent substrate" characteristics.

3 us7560738



The patents on March 11, 2005 by the crystal power application, and in 2009 invention patents authorized on July 14.


The patent of the principal right requirements:



Transparent substrate, more than the LED chip, wire string and connect.


Directly to a wire filament encased "more chips in series" characteristics.

4 us8240881



The patents on November 13, 2008 by the crystal power application, and in 2012 invention patents authorized on August 14.


The patent of the principal right requirements:



LED chips encapsulation in a transparent substrate, to filament "transparent substrate" characteristics of the packaging.


It is almost a ", a remarkable patents. Patent technology solutions, originally is chip encapsulation to transparent substrate first, then into encapsulation stents. The plan itself is historical development proved that no application prospect, but the "LED chips encapsulation in a transparent substrate is hit filament encapsulation.


Patent layout, many patent technology solution appears to be no practical significance, but scattered in the patent technology of small points, are likely to be inserted in the technology development direction of litigation.

5 us8791467



On May 11, the patent in 2011 by the crystal power application, and in 2014 invention patents authorized on July 29.


The patent of the principal right requirements:



The LED chip adhere to a high thermal conductive substrate.


Although the patent itself technology program for red chips in the substrate, but here the chips adhere to a high thermal conductive substrate "is one of the defining characteristics of a wire filament encased.


Crystal electricity for use "patent layout + write expand the scope of patent document" form of patent protection network method, is very skilled.


6 us9065022



The patents on March 18, 2013 by the crystal power application, and on June 23, 2016 invention patents authorized.


The patent of the principal right requirements:



Filament with LED light source, the realization of wide Angle light bulb.


Filament lamp has been widely attention in 2013, many manufacturers are research on how to implement large Angle of the light bulb with a filament, but didn't take the technical plan to apply for patent in the United States.


Crystal electric keenly capture the market prospects, the identity of the upstream chip manufacturers with a patent application of downstream products of the layout.


In recent years, in the LED lighting products price and profit plunge industry background, the filament lamp is different the bulge, popularity. The past the threshold of the filament lamp is to process and yield, crystal electricity today put a wire filament encased patent threshold also moved out.


Crystal electricity through the integrated use of a variety of patent layout method, realized the filament encapsulation comprehensive patent layout.


1, buy patent filing date very early basis.


2, use "oriented technology patent layout + write expand the scope of patent document" the method of formation of patent protection network.


3, focus on market, patent layout covering the industrial chain.
