In reply to Registered mark in bilingual logo:
I'm not as knowledgeable as John concerning the traditional rules of kasheeda placement, but even if I were I might actually shoot for -what must be- a superset of those rules: if it looks good, it is good. However, in this case at least it doesn't. :-/ You could make the kasheeda in the first word longer to end up with a nice symmetry, but I would actually agree with John that -at least in this case- no kasheedas at all might be best, especially considering the Latin is so dense.
Speaking of the Latin, there's something funny about it - it's like a distorted Futura. It's pudgy, and the spacing is very uneven. Also, the Latin is rather conventional while the Arabic is somewhat progressive (especially that 'ayn).
Then there's the problem of apparent size/importance (marginally related to kasheeda inclusions). By being both smaller and lighter the Arabic seems far less important. On the other hand this logo might need that feature - it's hard to know from the outside.
Concerning your original question, I'd suggest trying something that many designers would consider gimmicky: try making the dot of the jeem coincide with the dot of the "i", and make that the (R) sign! You might have to make the Arabic longer/bigger, but for one thing that would address the apparent importance issue above.
Lastly, the dots of the yaa' aren't sitting happy in relation to the "el".
