    The Sharpy probably isn't a good example to hold up in this case given that it was predated by the Elation Platinum 5R by at least a year I believe. A good example though of multiple companies developing very similar tech based on the availability of a light source.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    The problem with them pursuing the Europeans is its only going to harm European businesses. Honestly, if that is the issue then I'd simply set up a direct sales department in China and ship direct from there. Keep the service centre in Europe for convenience.

    Let me state that Kvant uses the Arctos Patent of knife-edging. As such they pay for it's use.That's fine with me, I don't care.
    Our system does NOT use knife edging.

    According to a leading patent office in The Netherlands, the EU patent system states a broad claim 1 and the rest of the adjacent claims are added to that to further specify the claim ( patent ). So Claim 1 is the most important one. If I review this it clearly states that parts of the refelected beams are cut off and do not contribute to the main beam. ( knife-edging ) . As our system does not use knife edging because all of the used beams are reflected fully, I see no wrong-doing on our part or on the part of the manufacturer, even if their module looks similar to existing modules of certain manufacturers.

    Looks can be deceiving...


    ..Don't judge a book by it's cover....or a laser for that matter...

    Peter,

    Your systems DO use knife edging. In fact the technique is an exact copy of KVANTS / Arctos's. Do you think KVANT would bother to use the Arctos patent if their design did not infringe on it?

    Have you even seen the inside of a Lightspace module? Actually, I'm sure you have probably compared it in order to gain sales...

    Eric, the patent is combining of the same wavelength via knife edging, not dichroic combining. Dichroic combining would never be patentable as there is prior knowledge going back how many years.

    I think this is completely fair enough. And too be honest I am sick to death of every unique lighting product being knocked off by the Chinese and undermining friends lighting companies, ie, sharpies, bee-eyes, martin Auras, et al.

    Dave,

    Apparently you know what knife-edging is and as such you will agree with me that knife-edging uses the most intense part of a beam to be reflected and lesser portions of the same beam are cut off. This generically leaves a result that behind the mirrors ( reflective surfaces ) a portion of the not-used beam shines onto any object that is behind that mirror.

    I assume you have opened such a module and have seen this knife-edging you state ? I have opened up one too and did not find any knife-edging, just simple reflection of collimated beams.

    Maybe your spam will stop soon
    If you believe this all to be spam, then why respond to it. Go play with your lasers...the grown ups are busy... :P

    I still do not see knife-edging. I see combining of beams, yes....but knife-edging is more then just combine beams. It refers to the combining of beams where *only* the "hottest" parts of the beams are used and the less intense sections of the beams are discarded...I believe I am repeating myself here...

    Also aren't you the Dave that is selling components for creating knife-edging combinations ?

    TBH I think you're being pedantic with the part about discarded parts of the beam or not. Fundamentally it's using mirrors to closely stack beams together.
    But I don't think you need to be pedantic to oppose this.
