tbh, not sure the patent is worth bothering with, I've read some very valid points in Duncan Bannantynes book.
long and the short is although you may have the patent, it is a very tricky thing to enforce. there are no "patent police", it would be down to you to bring an action against the person(s) infringing the patent, at your cost.
Consider the following as (extreme) examples:
1) Land Rover are so impressed with the product, the immediately copy it and sell it themselves as a genuine LR kit/product. Fair enough, you have the patent, but you have to enforce it. You, as an individual will then have to engage a solicitor at your cost to fight the full might of LR's legal team
2) Bloggs 4 x 4 copy the product and start selling it. Again, you launch an action against them to stop selling the kit and the court finds in your favour and awards you damages and costs. Bloggs then fold the company as insolvent and launch again as Bloggs2 4 x 4. Net result, you lose the lot, and end up liable for your legal fees.
3) Some chinese factory start knocking them out and selling them on ebay. the best you can hope for is ebay stop selling them (unlikely) but the seller then starts selling them with another id.
Not trying to discourage you in any way, but wouldn't get too hung up on the patent thing, you could lose a lot of time and money which could be better spent on marketing the product.
Genuinely wish you well with this though.
