Philipp is highly ranked in the leading legal directories, with Chambers (2025) reporting that clients find he "has deep expertise" and "is an excellent, well-spoken and pragmatic competition lawyer." Chambers (2024) reported that Philipp “receives considerable praise for his work both on EC or CMA behavioural investigations and on large-scale mergers” and that clients noted that: "He has a sharp and strategic mind, and thinks about the big picture without losing sight of the detail underpinning it", that he is a "hard worker" and is "very comfortable working on complex cases with multiple moving parts and stakeholders". Legal 500 (2024) noted that clients commented that he is "a pragmatic and innovative thinker".
