Just because you can register a company name, doesn’t mean that you can use it. And I am not at all surprised that Shell or SIPM have objected.
It’s unlikely that action against you for registering the company would succeed but they would almost certainly be able to take action against you for using the company name.
A lot depends on whether you want to do battle with a giant because they could tie you up in the legal costs for years even if there claim was not eventually successful.
The solicitors offer to change the name is ***** ***** bearing in mind that the solicitors have probably charge GBP500 to Shell just to get to this stage.
So you want to try going back to them and tell them that you would be happy to change the name but you want GBP500 in compensation and that if they don’t agree to that, you will bring this correspondence to the attention of the court as evidence of their unreasonable behaviour, if it gets that far.
It depends whether you want to bluff it.
Thank you for letting me assist you with your legal question. I am glad that I was able to help.
I am not certain whether that answers the question for you or not, but I am happy to answer any specific points arising from this.
It will be my pleasure to help you again either further with this or any future questions you have
