Locating a commercial partner company may be the desired scenario to establish your technology and business. The good news is that larger companies are always on the lookout to extend their market presence by diversification - and your device may fill their void. However, you have to show an initial element of success in placed units, established customers and a 'hockey stick' type growth curve. Partner companies will not budge only because they like your technology.
Furthermore, a marriage of partners is sometimes difficult to implement. Depending on the size of the partner company, it takes time to get all decision makers informed and bring them on one page. If a co-marketing agreement is implemented, the challenge for your technology becomes whether your new partner really is really committed to push your technology through its own sales channels, next to their established product lines.
