We scored 8 Port Huron intellectual property lawyers on nine factors, weighted as shown. A law firm is ranked when its practice area is confirmed and it has 3 or more Google reviews or a claimed profile. A law firm with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed November 9, 2026.
Paid placement never changes a rank or score. Attorney advertising businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
