Patent infringement and other matters
In manufactured products, infringement of structural, composition and process patents can often be revealed by microscopic examination of the material or device. We look at the structure to see what it is (for comparison with a designed structure) and to see what it says about the process that formed the structure. The AFM is used to examine surfaces (either normal external surfaces or interior structures revealed by delamination, cutting, etc.) and near-surface forces. When 3-dimensional structures are involved, when roughness is an issue, when contaminants are suspected, when electric or magnetic fields are present, and in many other situations, Atomic Force Microscopy (AFM) can provide unique insights.
A detailed look at material structure can be important when an accident has caused injury or death, when product tampering or counterfeiting is suspected, and in trade disputes.
Other AFM Applications
In addition to the casework examples above, there are literally hundreds of other established, well-accepted AFM applications, and more are waiting to be discovered. Please see a partial list of materials and devices we have personally examined and please explore the rest of our web site. Wondering whether we can help you win your case? Just ask.
We know our limits
No analytical instrument has unlimited application. We know what AFM can and can't do and when it is being misused. When opposing parties have AFM experts of their own, it can't hurt that we "helped write the book" on limitations of this technique. Finally, we know when other techniques can be used to complement AFM and make a more complete picture.
Communication is Important to us
"Atomic Force Microscope" sounds exotic, doesn't it? It really isn't. Working with hundreds of clients has taught us ways to express how AFM works and what AFM does in simple, concise terms, drawing appropriate analogies to everyday experiences. We are skilled at organizing data and presenting images that accurately support and illustrate our conclusions.
