The English word 'paternal' is often used in fixed phrases like 'paternal grandmother'. In Japanese, you cannot simply use an adjective equivalent; you must use the construction 父方の (father's side) + relative term. Saying 父親の祖母 would be confusing because it could mean 'father's grandmother' (i.e., great-grandmother).
The pattern is symmetric: 父方の (paternal) and 母方の (maternal). For example, 父方の祖父 (paternal grandfather) vs. 母方の祖父 (maternal grandfather).
