h-index and patent citation This question arises because I noticed in the past the patent articles in my Google scholar was cited and included in the rank for h-indexing. 
Since last year, these citations were removed, only to find out that they are included back.

My question, should citation on the patent article be included for h-indexing ? 

Note: They can influence a lot with inclusion and without.
Why not?  Patent article is also your work published so it should be included in h-index and all other indices for that matter.

That being said, this is my opinion, not an expert advice (Thanks to @iayork for pointing it out).  Discussion in the comments.  But the fact that Google Scholar list patents in your profile and their citations are used to calculate h-index, I say it is okay to have patent citations in your h-index.
