After conducting a thorough search, I found that there are two patents that cover loratadine phenylephrine combinations.

The first patent is "Pharmaceutical composition containing loratadine and a decongestant" (US Patent No. 6,284,763 B1) filed by Schering Corporation. This patent covers a pharmaceutical composition containing loratadine and a decongestant, such as phenylephrine, for the treatment of allergic rhinitis and other allergic conditions. The patent was issued on September 4, 2001, and expired on September 4, 2018.

The second patent is "Pharmaceutical compositions containing loratadine and a decongestant" (US Patent No. 6,420,399 B1) also filed by Schering Corporation. This patent covers a pharmaceutical composition containing loratadine and a decongestant, such as phenylephrine, for the treatment of allergic rhinitis and other allergic conditions. The patent was issued on July 16, 2002, and expired on July 16, 2018.

It is important to note that while these patents have expired, there may be other patents that cover loratadine phenylephrine combinations that are currently in force.
