The small business faces a hard climb in disputes like this. The big companies, with legal staff or lawyers on contract, can play this out for years, and sue, settle, or negotiate to suit their needs and sales strategies. Some deal that cuts both parties a piece of the action, if that can be figured out, is probably the best for two small businesses at loggerheads. Hope something good happens from this. I hope the other party realizes they could both go under. The pipe community is small and could just boycott a product they perceive as a ripoff.
