First of all.. Why don't you think of a patent ? If you really have the great innovative idea, then File a patent before launch.

Now you 've launched. But let's think one step earlier. What was your market ? Do you have connections with the suppliers ? Users ?

Retaining your customer base is one of the pillars for your success, no matter who is competing with you. To keep and expand your customers, make sure you are excellent on customer serivce to retain the current , and also the business development to expand to new ones.

You started a porduct.. Brand It ! Be the market leader. It will be very evident that the next one is just a copy. It is still in your favour , even , if they just thrive to be like you. But in the same time, you need to keep the brand by continuous improvement. Analyse your competitors and include new features on your products at a competitive price.

Make sure you are always one step ahead with innovation.. This will always keep you a head. Operational large scale production is not always the ideal way to keep you in the market, unless you are really delivering a Low Cost product with a stable good reliability and acceptable quality at that price. Always look to be differentiated.

Some , non appealing to lots of entrepreneurs , ideas are thinking of merges with the clones, or acquiring one if you have the fund, or even be acquired by one. It is not to kill the clone. It is to have their market share too..i.e. to expand yours, and instead of killing your operation expenses just for the sake of competition, you will have a stable relaxed market that you can focus on dominating with more efficiency and quality and new features before a new clone starts so you make it harder for the next new comer to compete with you .

Good Luck !
